Employment/Purpose

A columnlayout is a layout which can have multiple columns, and each column may have any number of panels placed vertically with different height. When using Columnlayout, you have to assign width (either percent or pixel) on every Columnchildren, or the result might depend on the browser and not as expected.

• Each column may have any number of any type of components since ZK6.

Example

Example for ZK5 or before:

<columnlayout>
    <columnchildren width="30%" style="padding: 5px">
        <panel height="100px" title="column1-1" closable="true" collapsible="true"
            border="normal" maximizable="true" style="margin-bottom:10px">
            <panelchildren>Panel</panelchildren>
        </panel>
        <panel height="100px" framable="true" title="column1-2"
