# GridListTileBar API

<p class="description">The API documentation of the GridListTileBar React component. Learn more about the props and the CSS customization points.</p>

## Import

```js
import GridListTileBar from '@material-ui/core/GridListTileBar';
// or
import { GridListTileBar } from '@material-ui/core';
```

You can learn more about the difference by [reading this guide](/guides/minimizing-bundle-size/).



## Component name

The `MuiGridListTileBar` name can be used for providing [default props](/customization/globals/#default-props) or [style overrides](/customization/globals/#css) at the theme level.

## Props

| Name | Type | Default | Description |
|:-----|:-----|:--------|:------------|
| <span class="prop-name">actionIcon</span> | <span class="prop-type">node</span> |  | An IconButton element to be used as secondary action target (primary action target is the tile itself). |
| <span class="prop-name">actionPosition</span> | <span class="prop-type">'left'<br>&#124;&nbsp;'right'</span> | <span class="prop-default">'right'</span> | Position of secondary action IconButton. |
| <span class="prop-name">classes</span> | <span class="prop-type">object</span> |  | Override or extend the styles applied to the component. See [CSS API](#css) below for more details. |
| <span class="prop-name">subtitle</span> | <span class="prop-type">node</span> |  | String or element serving as subtitle (support text). |
| <span class="prop-name">title</span> | <span class="prop-type">node</span> |  | Title to be displayed on tile. |
| <span class="prop-name">titlePosition</span> | <span class="prop-type">'bottom'<br>&#124;&nbsp;'top'</span> | <span class="prop-default">'bottom'</span> | Position of the title bar. |

The `ref` is forwarded to the root element.

Any other props supplied will be provided to the root element (native element).

You can override the style of the component thanks to one of these customization points:

- With a rule name of the [`classes` object prop](/customization/components/#overriding-styles-with-classes).
- With a [global class name](/customization/components/#overriding-styles-with-global-class-names).
- With a theme and an [`overrides` property](/customization/globals/#css).

If that's not sufficient, you can check the [implementation of the component](https://github.com/mui-org/material-ui/blob/master/packages/material-ui/src/GridListTileBar/GridListTileBar.js) for more detail.
