# @backstage/ui ## 0.16.0 ### Minor Changes - fc4e624: `Combobox` now supports async collections, incremental loading, client and server search, and rich or custom item rendering. Loading placeholders expose `.bui-ComboboxLoading` and `.bui-ComboboxLoadingRow`, and stale visible results expose `data-stale` on `.bui-ComboboxList`. **BREAKING**: The public `ComboboxProps` interface is now a union type. **Migration:** **Required on upgrade:** Replace interfaces that extend `ComboboxProps` with type intersections. ```diff - interface MyComboboxProps extends ComboboxProps { - trackingId: string; - } + type MyComboboxProps = ComboboxProps & { + trackingId: string; + }; ``` **Optional migration away from deprecated APIs:** Prefer `id` instead of `value` for plain options. Existing array-valued options using `value` remain supported as a deprecated compatibility path, but new option content fields and async option sources require `id`. Move input state and custom filtering into the nested `search` configuration: ```diff - + ``` The existing top-level input state props remain supported as a deprecated compatibility path for plain-array `options`. **Affected components:** Combobox - fc4e624: `Select` now supports async collections, incremental loading, client and server search, and rich or custom item rendering. Loading placeholders expose `.bui-SelectLoading` and `.bui-SelectLoadingRow`, and stale retained results expose `data-stale` on `.bui-SelectList`. **BREAKING**: The public `SelectProps` interface is now a union type, and Select popover list content is no longer a direct child of `.bui-SelectPopover`. **Migration:** **Required on upgrade:** Replace interfaces that extend `SelectProps` with type intersections. ```diff - interface MySelectProps extends SelectProps { - trackingId: string; - } + type MySelectProps = SelectProps & { + trackingId: string; + }; ``` Update CSS selectors that rely on list content being a direct child of `.bui-SelectPopover`. Select popovers now use the standard BUI Popover content structure, with contents wrapped in `.bui-Box.bui-PopoverContent`. The existing `.bui-Popover.bui-SelectPopover` root classes are unchanged. **Optional migration away from deprecated APIs:** Prefer `id` instead of `value` for plain options. Existing array-valued options using `value` remain supported as a deprecated compatibility path, but new option content fields and async option sources require `id`. Replace `searchable` and `searchPlaceholder` with nested `search` configuration: ```diff - ``` **Affected components:** Select ### Patch Changes - 3d6c2e4: Updated the dark theme neutral background tokens to provide clearer contrast between neutral surfaces. - c86efcd: Fixed the Table component not filling its container width in Firefox. The `overflow` style is now applied to a wrapper element instead of the `` element directly, which avoids a Firefox behavior where non-visible overflow on tables causes them to shrink-wrap to content size. - adf94f5: Make Skeleton component background aware, automatically adjusting its color to maintain visible contrast against neutral parent surfaces. **Affected components:** Skeleton - b06b3c7: Fixed header tab links to respect the configured router `basename`. **Affected components:** Header - 14a101f: Switch now adapts its track and thumb colors based on the background context of its parent container, and uses the accent token family when selected. **Affected components:** Switch - 66c4e55: Fixed tab indicator not updating position when tab content changes width dynamically. - b33bb24: Added a new `NumberField` component for numeric input with support for min, max, step, and keyboard increment/decrement. **Affected components:** NumberField - 350407d: Fixed async pagination in `Combobox` and `Select` popovers so additional pages load as users scroll instead of loading every page immediately. `Combobox` now uses `.bui-PopoverContent` as its scroll container, while all `Select` variants use the new `.bui-SelectResults` results container. Searchable `Select` keeps its search field fixed while results scroll. The new public classes `.bui-SelectContent` and `.bui-SelectResults` expose this layout for theme customization. **Affected components:** Combobox, Select - e989f95: Fixed `Combobox` client search crashing when used with plain options. **Affected components:** Combobox - 1f709a3: Fixed Header breadcrumb typography so it remains consistent when component styles are loaded in different orders. **Affected components:** Header - 5d80f77: Introduces a new set of semantic color token families — Accent, Announcement, Warning, Negative, and Positive — each providing a consistent set of background, foreground, and border tokens for both light and dark themes. A gray scale (`--bui-gray-1` through `--bui-gray-11`) and updated foreground tokens are also included. The previous tokens remain in place for backward compatibility but are now deprecated and will be removed in a future release. **Migration:** **Neutral backgrounds** The neutral background tokens keep their existing names (`--bui-bg-app`, `--bui-bg-neutral-1` through `--bui-bg-neutral-4`) but are updated with new solid-color values for both light and dark themes. No token renaming is required. The `-hover`, `-pressed`, and `-disabled` interaction variants of these tokens are deprecated and should be removed. **Foreground** | Deprecated | Replacement | | ------------------ | ----------------------- | | `--bui-fg-danger` | `--bui-fg-negative` | | `--bui-fg-success` | `--bui-fg-positive` | | `--bui-fg-info` | `--bui-fg-announcement` | **Accent** | Deprecated | Replacement | | ------------------------- | -------------------------- | | `--bui-bg-solid` | `--bui-accent-bg` | | `--bui-bg-solid-hover` | `--bui-accent-bg-hover` | | `--bui-bg-solid-disabled` | `--bui-accent-bg-disabled` | | `--bui-fg-solid` | `--bui-accent-fg` | | `--bui-fg-solid-disabled` | `--bui-accent-fg-disabled` | **Positive** | Deprecated | Replacement | | ------------------------ | --------------------------- | | `--bui-bg-success` | `--bui-positive-bg-subdued` | | `--bui-fg-success-on-bg` | `--bui-positive-fg-subdued` | | `--bui-border-success` | `--bui-positive-border` | **Negative** | Deprecated | Replacement | | ----------------------- | --------------------------- | | `--bui-bg-danger` | `--bui-negative-bg-subdued` | | `--bui-fg-danger-on-bg` | `--bui-negative-fg-subdued` | | `--bui-border-danger` | `--bui-negative-border` | **Warning** | Deprecated | Replacement | | ------------------------ | -------------------------- | | `--bui-bg-warning` | `--bui-warning-bg-subdued` | | `--bui-fg-warning-on-bg` | `--bui-warning-fg-subdued` | | `--bui-border-warning` | `--bui-warning-border` | **Announcement** | Deprecated | Replacement | | --------------------- | ------------------------------- | | `--bui-bg-info` | `--bui-announcement-bg-subdued` | | `--bui-fg-info-on-bg` | `--bui-announcement-fg-subdued` | | `--bui-border-info` | `--bui-announcement-border` | ## 0.15.1-next.0 ### Patch Changes - 14a101f: Switch now adapts its track and thumb colors based on the background context of its parent container, and uses the accent token family when selected. **Affected components:** Switch - b33bb24: Added a new `NumberField` component for numeric input with support for min, max, step, and keyboard increment/decrement. **Affected components:** NumberField - 1f709a3: Fixed Header breadcrumb typography so it remains consistent when component styles are loaded in different orders. **Affected components:** Header - 5d80f77: Introduces a new set of semantic color token families — Accent, Announcement, Warning, Negative, and Positive — each providing a consistent set of background, foreground, and border tokens for both light and dark themes.

When `true`, the title-and-actions bar stays fixed to the top of its scroll container while the rest of the header (tags, description, metadata) scrolls away. The sticky bar background color automatically matches the container surface using the bg-consumer system. **BREAKING**: Removed the main header class from the `Header` component. Custom styles that target this class should be updated to target the component sections that remain. **Affected components:** Header ### Patch Changes - 3846774: Added missing dependencies that were previously only available transitively. - e8a1a35: Added `isPending` prop to Alert, Button, ButtonIcon, Table, and TableRoot as a replacement for the `loading` prop, aligning with React Aria naming conventions. The `loading` prop is now deprecated but still supported as an alias. CSS selectors now use `data-ispending` instead of `data-loading` for styling pending states; `data-loading` is still emitted for backward compatibility but will be removed alongside the `loading` prop. **Affected components:** Alert, Button, ButtonIcon, Table, TableRoot - 37535b2: Added a public `--bui-bg-inherit` CSS variable that resolves to the background color of the nearest enclosing bg provider (`Box`, `Flex`, `Grid`, `Card`, `Accordion`, or any element with a `data-bg` attribute), falling back to `--bui-bg-app`. Use it from CSS for sticky or fixed elements that need to match their surrounding surface without hardcoding a specific level. ```css .searchBarContainer { position: sticky; top: 0; background-color: var(--bui-bg-inherit); } ``` As part of this change, the `data-bg` painting rules previously duplicated in `Box`, `Flex`, `Grid`, `Accordion`, and `Card` have been centralized into a single source in `core.css`. Painting and component behavior are unchanged for all existing usages, with one minor expansion: any element with a `data-bg` attribute (including provider elements and any element that sets it directly) is now painted, not only `Box`/`Flex`/`Grid`/`Card`/`Accordion` elements. - e2d9831: Tightened React Aria dependency version ranges from `^` to `~` to prevent unintended minor version upgrades. - e7fc79f: Added support for grouping options into sections in the Select component. You can now pass section objects with a `title` and a nested `options` array alongside (or instead of) regular options to render grouped dropdowns with section headers. **Affected components:** Select - 76635ae: Disabled `Card` scroll shadow in browsers that don't support `animation-timeline: scroll()`. Prevents the shadow from being always visible over the `CardBody` when there's nothing to scroll or the body is not scrolled. **Affected components:** Card - de75f7c: Fixed `CardBody` showing an unwanted scrollbar when constrained below the scroll shadow height. **Affected components:** Card - a42766e: Fixed dark mode background for Dialog component by correcting the theme attribute selector from `data-theme` to `data-theme-mode`. **Affected components:** Dialog - c6fc76f: Fixed an issue where the active tab indicator would disappear shortly after page load for uncontrolled Tabs. **Affected components:** Tabs - 5520e07: Updated field components to grow within flex layouts instead of forcing their width to remain fixed. - 11699ac: Updated `PasswordField` to visually match `TextField`, including consistent focus rings, error states, disabled appearance, and background colour behaviour. **Affected components:** PasswordField - d1be10c: Updated React Aria dependencies to v1.17.0 and migrated imports from individual `@react-aria/*` and `@react-stately/*` packages to the monopackages (`react-aria`, `react-stately`). This fixes a type resolution error for `@react-types/table` that occurred in new app installations. - c96e2b3: Added `description`, `tags`, and `metadata` props to the `Header` component. The `description` prop accepts a markdown string with support for inline links. The `tags` prop renders a row of text or link items above the title. The `metadata` prop renders key-value pairs below the description. The `breadcrumbs` prop has been deprecated and will be removed in a future release. **Affected components:** Header - 4bb649d: Fixed Table with row selection creating phantom scroll height on ancestor elements by establishing a containing block for visually-hidden checkbox inputs. **Affected components:** Table, TableRoot - f635139: Limited `@remixicon/react` dependency to versions below 4.9.0 due to a license change in that release. - 5b85902: Fix `Card href=...` not showing a focus indicator on keyboard navigation. `Link` now composes `useFocusRing`, emits `data-focus-visible`, and renders a `--bui-ring` outline when keyboard-focused. The Card's existing focus-ring CSS matches when the trigger is focused. _Affected components_: Card, Link - 23ee789: Added invalid-state styling for Checkbox and corresponding Storybook variants for verification. **Affected components:** Checkbox, CheckboxGroup - 38bb056: Adjusted PluginHeader spacing and borders so headers with and without tabs align more consistently with surrounding page content, including when paired with page headers. **Affected components:** PluginHeader, Header - df705bb: Fixed external URLs in BUI link components being rewritten as in-app paths when the app is served under a non-root base path. Absolute URLs (`http://`, `https://`, `//`, `mailto:`, `tel:`) are now passed through unchanged. Internal `href` values are resolved against the current `basename` exactly once, which also fixes a latent issue where internal link clicks under a non-root base path could navigate to a URL with the `basename` prefix doubled. **Affected components:** ButtonLink, Card, Link, Menu, Tab, Table, Tag - 3e0ff6c: Added container alignment to `Header` sections so tags, title actions, descriptions, metadata, and tabs use the same width as surrounding page content. **Affected components:** Header - b67a862: Updated Storybook development tooling for `@backstage/ui` to version 10.4. - d726bcd: Added new `DatePicker` component — combines a date field and a calendar popover for selecting a date, built on React Aria with full keyboard and screen reader accessibility. Uses BUI design tokens throughout, including auto-incremented backgrounds via the bg consumer pattern. **Affected components:** DatePicker - 401916d: Added new `DateRangePicker` component — combines two date fields and a calendar popover for selecting a date range, built on React Aria with full keyboard and screen reader accessibility. Uses BUI design tokens throughout, including auto-incremented backgrounds via the bg consumer pattern. - 25909ba: Added `searchDebounceMs` and `filterDebounceMs` options to `useTable` in `complete` mode. Both default to `0` (no debounce, no observable change for existing consumers); set them to defer the client-side filter/search/sort pipeline on large datasets without reimplementing input-layer debouncing. The controlled `search` / `onSearchChange` and `filter` / `onFilterChange` callbacks continue to fire on every change. **Affected components:** Table - ddca41f: Added a new `Combobox` component. It pairs a text input with a filterable dropdown of options and supports single selection, sectioned options, icons, sizes, and custom typed values via `allowsCustomValue`. **Affected components:** Combobox ## 0.15.0-next.3 ### Patch Changes - 4bb649d: Fixed Table with row selection creating phantom scroll height on ancestor elements by establishing a containing block for visually-hidden checkbox inputs. **Affected components:** Table, TableRoot - d726bcd: Added new `DatePicker` component — combines a date field and a calendar popover for selecting a date, built on React Aria with full keyboard and screen reader accessibility. Uses BUI design tokens throughout, including auto-incremented backgrounds via the bg consumer pattern. **Affected components:** DatePicker ## 0.15.0-next.2 ### Patch Changes - 37535b2: Added a public `--bui-bg-inherit` CSS variable that resolves to the background color of the nearest enclosing bg provider (`Box`, `Flex`, `Grid`, `Card`, `Accordion`, or any element with a `data-bg` attribute), falling back to `--bui-bg-app`.

Also introduced `--bui-shadow` token for consistent elevation styling across overlay components (Popover, Tooltip, Menu). **Affected components:** Popover - 973c839: Fixed Table sorting indicator not being visible when a column is actively sorted. **Affected components:** Table, Column - df40cfc: Fixed Menu component trigger button not toggling correctly. Removed custom click-outside handler that was interfering with React Aria's built-in state management, allowing the menu to properly open and close when clicking the trigger button. **Affected components:** Menu - b01ab96: Added support for column width configuration in Table component. Columns now accept `width`, `defaultWidth`, `minWidth`, and `maxWidth` props for responsive layout control. **Affected components:** Table, Column - b4a4911: Fixed SearchField `startCollapsed` prop not working correctly in Backstage UI. The field now properly starts in a collapsed state, expands when clicked and focused, and collapses back when unfocused with no input. Also fixed CSS logic to work correctly in all layout contexts (flex row, flex column, and regular containers). **Affected components:** SearchField - b3253b6: Fixed `Link` component causing hard page refreshes for internal routes. The component now properly uses React Router's navigation instead of full page reloads. - fe7fe69: Added support for custom pagination options in `useTable` hook and `Table` component. You can now configure `pageSizeOptions` to customize the page size dropdown, and hook into pagination events via `onPageSizeChange`, `onNextPage`, and `onPreviousPage` callbacks. When `pageSize` doesn't match any option, the first option is used and a warning is logged. **Affected components:** Table, TablePagination - cfac8a4: Fixed missing border styles on table selection cells in multi-select mode. **Affected components:** Table - 2532d2a: Added `className` and `style` props to the `Table` component. **Affected components:** Table ## 0.11.0-next.1 ### Minor Changes - 243e5e7: **BREAKING**: Redesigned Table component with new `useTable` hook API. - The `Table` component (React Aria wrapper) is renamed to `TableRoot` - New high-level `Table` component that handles data display, pagination, sorting, and selection - The `useTable` hook is completely redesigned with a new API supporting three pagination modes (complete, offset, cursor) - New types: `ColumnConfig`, `TableProps`, `TableItem`, `UseTableOptions`, `UseTableResult` New features include unified pagination modes, debounced query changes, stale data preservation during reloads, and row selection with toggle/replace behaviors. **Migration:** 1. Update imports and use the new `useTable` hook: ```diff -import { Table, useTable } from '@backstage/ui'; -const { data, paginationProps } = useTable({ data: items, pagination: {...} }); +import { Table, useTable, type ColumnConfig } from '@backstage/ui'; +const { tableProps } = useTable({ + mode: 'complete', + getData: () => items, +}); ``` 2. Define columns and render with the new Table API: ```diff -
