Name	Type	Description
animate	`boolean`	Sets the animate state of the PanelBar (see example).
expandMode	`PanelBarExpandMode`	Sets the expand mode of the PanelBar through the `PanelBarExpandMode` enum (see example). The available modes are: `"single"`—Expands only one item at a time. Expanding an item collapses the item that was previously expanded. `"multiple"`—The default mode of the PanelBar. Expands more than one item at a time. Items can also be toggled. `"full"`—Expands only one item at a time. The expanded area occupies the entire height of the PanelBar. Requires you to set the `height` property.
height	`any`	Sets the height of the component when the `"full"` expand mode is used. This option is ignored in the `"multiple"` and `"single"` expand modes.
selectable	`boolean`	Allows the PanelBar to modify the selected state of the items.
items	`PanelBarItemModel[]`	Sets the items of the PanelBar as an array of `PanelBarItemModel` instances (see example).
keepItemContent	`boolean`	When set to `true`, the PanelBar renders the content of all items and they are persisted in the DOM (see example). By default, this option is set to `false`.
