Hi

Does anyone know How you can use a Collapsible set with tabs

On the left of my page I want a Collapsible set  acting as a menu. Some items will have children and some not.

I want the items without children to change the tab directly but the items with children should expand.

(Then children in this case change the tabs)

I have an example at

I can not get the header items without children to change tabs or not to expand.

Also the tab content shows by default.

Is the a better way to achieve the result I want ?

Thanks for any help
