Types in JavaScript Sidebar control

The Sidebar component’s expand behaviour can be modified based on the purpose of use.

Expanding types of Sidebar

The Sidebar can be set to initialize based on four different types that are consistent with the main component as explained below. When dataBind is invoked, this applies the pending property changes immediately to the component.

Item Description
Over Sidebar floats over the main content area.
Push Sidebar pushes the main content area to appear side-by-side, and shrinks the main content within the screen width.
Slide Sidebar translates the x and y positions of main content area based on the Sidebar width. The main content area will not be adjusted within the screen width.
Auto Sidebar with Over type in mobile resolution, and Push type in other higher resolutions.

Auto is the default expand mode. Sidebar with type Auto will always expand on initial rendering, irrespective of enableDock and isOpen properties.

In the following sample, the types of Sidebar are demonstrated.
