Variations in Vue Sidebar component

17 Feb 202524 minutes to read

The Sidebar component’s expand behavior can be modified based on its intended 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, it 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 to fit within the screen width.
Slide	Sidebar translates the x and y positions of the main content area based on the Sidebar width.
Auto	Sidebar with Over type in mobile resolution, and Push type in other higher resolutions.

Auto is the default expand mode.

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