Listbox Button
No screenshot yet.
NOTE: we are in the process of restructuring the Autocomplete, Combobox, Listbox and Select patterns. Please bear with us.
The listbox pattern is a JavaScript widget. It is a button that opens a listbox in a flyout.
Because it is not a form control, the button value will not be passed to the server. If you require this behaviour, please consider the select pattern instead.
Do not call a listbox button a "dropdown"! The term "dropdown" is ambiguous and could be confused with a menu, combobox, select or any other kind of overlay that "drops down". If you must, call it a dropdown listbox.
You can take a look at the listbox button pattern in action on our examples site.
You can get a quick idea of the required markup structure by viewing our bones project.
widget: the pattern as a whole, comprised of the parts below
button: the button that opens the flyout
