Hi there

I am looking for a way to do the following:

--

For example:

Level 1 has: 

Button 1  |  Button 2  |  Button 3  |  Button 4

Level two:

Under Button 1 it has:

Button 1.1  |  Button 1.2  |  Button 1.3

Under Button 2 it has:

Button 2.1  |  Button 2.2

...

I wanted to tell on master page saying that:
Get all level 2 under Button 2... how would I do that..

Thanks
Raheel
