Properties and Features

Caption

Available for ZK:

Since 6.5.0

A layout region may have a caption, which is specified by declaring a child component <caption>.

<borderlayout>
	<north>
		<caption label="search" image="/img/live.gif"/>
		<div>
		Content
		</div>	
	</north>
</borderlayout>

Closable

Since 8.5.2 Default: true

Whether users can open or close the region. Require collapsible="true". Notice you need to click the icon on the title or on the splitter to open/close a region. Clicking a title slides a region instead of opening it.

Slidable

Since 8.5.2 Default: true

Whether users can slide (preview) the region when clicking on the title of the collapsed region. It opens the region like a drawer overlapping on the <center>, so it doesn't affect the size of <center> which is different from opening the region. Require collapsible="true".
