The Wijmo Expander widget (wijexpander) allows you to show or hide embedded or external content within an expanding panel using various animation effects. The expanding content can be shown or hidden by clicking on the expander header.

Multiple expand directions
The jquery UI expander widget is able to expand in several different directions. You can set whether the control expands to the Top, Right, Bottom, or Left.

External content
You can show external content in the dialog window of Wijmo Expander. This can be content of another web page in your project or content of a website outside of your project.
Animation
Wijmo Expander includes built-in animation effects, such as linear or elastic easing, that can be set when the control is expanded or collapsed. Customize how animations are transitioned using the built-in animation transition option. You also have the ability to modify the length of the animation effects.
