BSP - Frame creation

Hi everybody,

i would like to know how can we create some kind of frame in BSP.

I've created my layout with HTML.

i've separated my layout in 3 parts: Head part, left part and right part.

When i try to insert some <htmlb> elements ( treeView) in my HTML layout in a particular part (left part for example), it doesn'work. My element appears correctly but I cannot use it.

It works only if i open a new window when calling HTMLB.

I think that it's not possible to mix html and htmlb elements.

So how can i divide my layout in several parts and how can i use htmlb in each parts of them?
