# Expand Mode

The PanelBar supports various expand modes.

The expand modes are:

* `single`—Expands only one item at a time. If you expand an item, the item that was previously expanded is collapsed.
* `multiple` (default)—Expands two or more items at a time. Items can also be toggled.
* `full`—Expands only one item at a time and requires you to set the `height` property. The expanded area occupies the entire height of the PanelBar.

To configure the expand modes, use the [expandMode](https://www.telerik.com/kendo-angular-ui-develop/components/layout/api/panelbarcomponent#expandmode) property of the PanelBar.
