**Purpose**: Displays attributes of the entity selected in a connected table widget, with flexible grid-based layout.

This is a **container widget** that holds an embedded layout grid. It contains nested `cf.platform.connectedSingleAttribute` widgets arranged in customizable rows and columns.

**Typical Workflow**:
1. First, configure `singleSelectionWidgetId` to connect to a table widget on the same page
2. Configure the `layout` using dedicated MCP Tools for Managing Embedded Layouts
3. Optionally set title, height, and frame visibility

**Key Attributes**:
- `singleSelectionWidgetId`: **Required first step** - ID of the table widget that provides entity selection events
- `cf.cplace.platform.attributesGroup.layout`: Grid-based layout defining how embedded attribute widgets are arranged

**Widget Behavior**:
- Widget subscribes to selection events from the connected table widget
- When user selects a row in the table, this widget refreshes to show attributes of that entity
- Currently only table widgets (`cf.cplace.platform.table`) can be used as selection sources

**Frontend Mode** (`cf.cplace.platform.useNewFrontend`):
- Controls whether the widget renders using the modern frontend implementation
- **Always set to `true`** for new implementations to enable the modern rendering pipeline
- When `true`, child Connected Single Attribute widgets inherit this setting automatically
