Before seeing the ZK Data binding concept , first let us learn the for each attribute in zk
The following zul file is simple which has the list items
<?page title="Example1" contentType="text/html;charset=UTF-8"?>
<zk>
<window title="Example1" border="normal">
Example for "for each"
<listbox>
<listitem label="Apple" />
<listitem label="Orange" />
<listitem label="Strawberry" />
</listbox>
</window>
</zk>
The output can be expected if you use for each attribute as follows
<?page title="Example2" contentType="text/html;charset=UTF-8"?>
<zk>
<window title="Example2" border="normal">
Example for "for each"
<listbox>
<listitem label="${each}"
forEach="Apple, Orange, Strawberry" />
</listbox>
</window>
</zk>
The forEach attribute is used to specify a collection of object such that the XML element it belongs will be evaluated repeatedly for each object of the collection.
