A list box presents a set of items from which the caller can select. You create a list box by using one or more OPTION elements inside a SELECT element.
The WTE renders a list box as a menu. That is, the WTE announces the list box and all its items, and then waits for the caller to make a selection by pressing the DTMF key associated with an item, or by speaking a word or phrase associated with an item.
You can create a multiselection list box by including the MULTIPLE attribute on the SELECT element. In this case, the caller is able to choose more than one item from the list. The announcement of a multiselection menu includes all audio items (either voice files or textual) gathered before the element, the cue-before CSS property and the VOICEFILE attribute on the SELECT element, the voice files and cues from all of the OPTION elements, and the cue-after CSS property on the SELECT element. When the caller makes a choice, the announcement of the menu starts from the item that is next to the one selected. If an error (either a time-out or a non-valid key) is detected, announcements of all menu items are rendered excluding those that were already chosen. Audio items on the SELECT control itself are always rendered.
