Use multiple tabbed panels

Tab panels can be displayed in any layout region, so that a view can include multiple tab panels defined in separate layout regions.

<layout type="borderLayout" id="mainLayout">
<north autoScroll="true" split="true" initialSize="300" minSize="100"/>
<center autoScroll="true"/>
</layout>
<layout type="borderLayout" id="projectLayout" containingLayout="mainLayout" region="north">
<west autoScroll="true" split="true" initialSize="300" minSize="100"/>
<center autoScroll="true"/>
</layout>
<layout type="borderLayout" id="actionLayout" containingLayout="mainLayout" region="center">
<west autoScroll="true" split="true" initialSize="300" minSize="100"/>
