Detailed Description

AjaxSelectionList provides a list component that supports keyboard navigation and component renderers. Externally, the component behaves like a form field, similar to WOPopUpButton except that it uses its component content as the renderer for each item instead of taking a displayString.

The javascript wrapper exposes events of the selection changing, the item being selected (via double-click or the enter key), and an item being deleted (with the delete key).

Author:: mschrag elementName (optional) the type of the list element inside the selection list (ul, ol, table) elementName (optional) the type of element for the wrapper (default to "a" to support tabbing, but presents some styling complexities in IE) list (required) the list to render item (required) bound for each item of the list selection (optional) the current selection mandatory (optional) if false, a null value will be prepended to the list. It is up to your component content to handle the null value to show a "No Selection" value. mandatory defaults to true. Mandatory does not imply any validation, it is the semantic equivalent of noSelectionString when compared to WOPopUpButton. id (optional) the id of the list class (optional) the css class of the list style (optional) the css style of the list name (optional) the form field name onchange (optional) the javascript to execute when the selection changes onselect (optional) the javascript to execute when the user presses enter or double-clicks ondelete (optional) the javascript to execute when backspace or delete is pressed focus (optional) if true, the selection list will be focused containerElementName the container element for this component, which is "a"
