PHP 클래스 Prado\Web\UI\WebControls\TListBox

TListBox displays a list box on a Web page that allows single or multiple selection. The list box allows multiple selections if {@link setSelectionMode SelectionMode} is TListSelectionMode::Multiple. It takes single selection only if Single. The property {@link setRows Rows} specifies how many rows of options are visible at a time. See {@link TListControl} for inherited properties. Since v3.0.3, TListBox starts to support optgroup. To specify an option group for a list item, set a Group attribute with it, $listitem->Attributes->Group="Group Name"; or in template
