# UIOptions

This prop can be used to customise UI of Excalidraw. Currently we support customising [`canvasActions`](#canvasactions), [`dockedSidebarBreakpoint`](#dockedsidebarbreakpoint) [`welcomeScreen`](#welcmescreen) and [`tools`](#tools).

<pre>
  &#123;
  <br /> canvasActions?: <a href="https://github.com/excalidraw/excalidraw/blob/master/src/types.ts#L372">
    CanvasActions
  </a>, <br /> dockedSidebarBreakpoint?: number, <br /> welcomeScreen?: boolean <br />

  }
</pre>

## canvasActions

This `prop` controls the visibility of the canvas actions inside the `menu`.

| Prop | Type | Default | Description |
| --- | --- | --- | --- |
| `changeViewBackgroundColor` | `boolean` | `true` | Indicates whether to show `Background color picker`. |
| `clearCanvas` | `boolean` | `true` | Indicates whether to show `Clear canvas` button. |
| `export` | `false` &#124; [`exportOpts`](#exportopts) | `object` | This prop allows to customize the UI inside the export dialog. By default it shows the `save file to disk`. For more details visit [`exportOpts`](#exportopts). |
| `loadScene` | `boolean` | `true` | Indicates whether to show `Load` button. |
| `saveToActiveFile` | `boolean` | `true` | Indicates whether to show `Save` button to save to current file. |
| `toggleTheme` | `boolean` &#124; `null` | `null` | Indicates whether to show `Theme toggle`. When defined as `boolean`, takes precedence over [`props.theme`](/docs/@excalidraw/excalidraw/api/props#theme) to show `Theme toggle`. |
| `saveAsImage` | `boolean` | `true` | Indicates whether to show `Save as image` button. |

```tsx live
function App() {
  const UIOptions = {
    canvasActions: {
      changeViewBackgroundColor: false,
      clearCanvas: false,
      loadScene: false,
    },
  };
  return (
    <div style={{ height: "500px" }}>
      <Excalidraw UIOptions={UIOptions} />
    </div>
  );
}
```

### exportOpts

The below attributes can be set in `UIOptions.canvasActions.export` to customize the export dialog.  
If `UIOptions.canvasActions.export` is `false` the export button will not be rendered.

| Prop | Type | Default | Description |
| --- | --- | --- | --- |
| `saveFileToDisk` | `boolean` | `true` | Indicates whether `save file to disk` button should be shown |
| `onExportToBackend` | `object` | \_ | This callback is triggered when the shareable-link button is clicked in the export dialog. The link button will only be shown if this callback is passed. |
| `renderCustomUI` | `object` | \_ | This callback should be supplied if you want to render custom UI in the export dialog. |

## dockedSidebarBreakpoint

This prop indicates at what point should we break to a docked, permanent sidebar. If not passed it defaults to [`MQ_RIGHT_SIDEBAR_MAX_WIDTH_PORTRAIT`](https://github.com/excalidraw/excalidraw/blob/master/src/constants.ts#L161).  
If the _width_ of the _excalidraw_ container exceeds _dockedSidebarBreakpoint_, the sidebar will be `dockable` and the button to `dock` the sidebar will be shown  
If user choses to `dock` the sidebar, it will push the right part of the UI towards the left, making space for the sidebar as shown below.

  return (

    </div>
  );
}
```
