# layout.panels

Part of [Layout](https://kernstra.com/docs/web-sdk/config/layout) in the Kernstra Web SDK 1.0.0 configuration reference.

- Type: `PanelDisplayMode`
- Default: `'auto'`
- Page: https://kernstra.com/docs/web-sdk/config/layout/panels

`'auto'` pushes the document aside at `comfortable` and switches to an overlay drawer at `compact` and below. The sidebar — one panel, with Pages, Outline, Attachments, Signatures and Comments as tabs — then floats over the document, and a backdrop appears that dismisses it when tapped. Force either behavior with `'push'` or `'overlay'`. On a tablet the sidebar always docks beside the page.

- `'auto'`: Default. Push at `comfortable`, overlay at `compact` and below.
- `'push'`: Always push the document aside.
- `'overlay'`: Always float over the document with a tap-to-dismiss backdrop.
