Panels and their panels are not usually in parent-child relationship.

Tabs is a group of radio buttons having
:checked state flag bound to :expanded/:collapsed
state of correspondent panel elements - divs or any other
display:block elements.

Tabs represent concept of only-one-from-many is expanded.
Visually tabs can presented in many ways.
This [1] is another tabs incarnation: only-one-from-many is visible.

There is also many-from-many switch (UI pattern if you wish).
In principle many-from-many switch is close to what collapsible tree is
using - many containers can be in expanded or collapsed state at the 
same time. Group of checkboxes that are bound to expanded/collapsed
panels is a good model of this.
