Questions tagged [expander]

An Expander control provides a way to provide content in an expandable area that resembles a window and includes a header.

jQuery Expander plugin: The Expander Plugin hides (collapses) a portion of an element's content and adds a "read more" link so that the text can be viewed by the user if he or she wishes. By default, the expanded content is followed by a "read less" link that the user can click to re-collapse it. Expanded content can also be re-collapsed after a specified period of time.

WPF Expander: Represents the control that displays a header that has a collapsible window that displays content.
