Introduction
The Kendo UI PanelBar widget is similar to a tabbed panel that contains a list of items grouped under different tabs or panes. In a PanelBar, these lists of items are stacked vertically, and each list item can be expanded to show you the content. This widget is particularly useful when the data can be grouped into multiple sections and there is a constraint on the available space to display this data. For example, all your contacts can be grouped by some category such as Favourites, Family, Friends, and Office Contacts; when you tap on one of the these categories, the panel would expand to show you the list of contacts that belong to that category.
