<jato:listbox>
Renders an HTML list as comprised of an HTML <input type="select"> element containing an arbitrary number of HTML <option> elements. This tag offers the convenience of treating the list as a single element and the flexibility of dynamic list content generation.
This tag is only valid when enclosed by both an HTML <form> element and a useViewBean, containerView, or tiledView tag. This tag may not contain any body content.
Example:
<jato:listbox name="itemSize" size="4" multiple="false"/>
The above would be rendered into the following HTML:
<select name="PageFoo.itemSize" size="4">
<option value="S">Small</option>
<option value="M">Medium</option>
<option value="L">Large</option>
<option value="XL">Extra Large</option>
</select>

name
|
The name of the DisplayField peer. This peer must be a child of the current parent ContainerView, TiledView, or ViewBean. The DisplayField name is resolved relative to the current parent view.
The view peer must be of type <JATO package>.view.html.SelectableGroup
This name may be a qualified view path, using forward slashes ("/") as delimiters. All components in the path except the last must refer to a ContainerView or a derivative of ContainerView (such as TiledView). Both relative and absolute paths are possible. If a name path begins with a forward slash, the name is assumed to be relative to the root view (the ViewBean). If the path does not begin with a forward slash, the name is assumed to refer to a child relative to the current container. Two dots ("..") may be used to refer to the container that is the parent of the current container.
Examples:
/header/orderList/customerName (absolute from root view)
orderList/customerName (relative to current container)
../footer/orderList/customerName (relative to parent)
