List
function List(multiSelect, rowCount)
Creates a list widget. Lists can only sensibly contain instances of
ListItem. Note that all the content-manipulation methods
except appendChild are linear-time in Internet Explorer.
Parameters:
multiSelect - (Optional) a boolean indicating whether or not the list should allow multiple items to be selected at once. Defaults to false.
rowCount - (Optional) an int indicating how many rows to display in the list. This parameter might be useless since lists will display as many items as can fit in their height. Defaults to 5 to garauntee that we get a list, and not a drop-down list.

WidgetList getSelection()

Returns:
this list's selection as a WidgetList
getValue

Parameters:
selection - a list of list items to select
setSelectionByValue
void setSelectionByValue(selection)
Selects the ListItems by their values as specified in
selection.
Parameters:
selection - An abstract_list, array or string specifying the items to select.
