# \&overlaycontrols

Viewer-Side Option! ([`&view`](/advanced-settings/mixer-scene-parameters/view.md), [`&scene`](/advanced-settings/mixer-scene-parameters/scene.md), [`&room`](/advanced-settings/setup-parameters/room.md))

## Options

Example: `&overlaycontrols`

| Value      | Description                                |
| ---------- | ------------------------------------------ |
| (no value) | Overlay control bar; do not reserve height |

## Details

* Keeps the user control bar overlayed on top of the video area instead of reserving a dedicated area below it. This avoids layout height changes when showing/hiding controls.
* Useful for tight layouts where vertical space is limited, or when combined with widgets/iframes.
* Related behavior: [`&controlbarspace`](/advanced-settings/buttons-and-control-bar-parameters/and-controlbarspace.md) forces a dedicated space for the control bar. Do not use both together.
* Mobile: behavior may vary depending on screen height; overlay avoids shrinking the grid area when controls appear.
