Does SmartGWT supports generation of subtabs? How to generate SubTabs using SmartGWT api?

Just use a TabSet as tab.pane in another TabSet.

Thanks for the reply...
I have successfully added the sub tab. But I am not able to remove the extra space generated between the main tabs and subtabs. How to reduce/remove that space ?

Tab: Home|Admin
SubTab : Below Admin I have: Profile|ChangePassword etc.
There is some gap/space between these tabs and subtabs. Similar space is getting created when even if I use ToolStrip. How to remove this space ?

Version: SmartClientPro, SmartGWT2.3

Any help ?
