Columnlayout

Employment/Purpose

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

[since 6.0.0]

Each column may have any number of any type of components.
