Specific UI interaction process

Hello,

I am checking out ngui 2 package and am trying to setup multiple tab dropdowns as in example 9 "quest log" scene. I have set all UI button tween components to OnSelect. Now my purpose is that when I select a certain menu tab option it needs to expand but with that al the other tabs collapse other than the selected tab.

On setting the trigger on UIButtonTween to OnSelect from OnClick I get the desired effect but the problem is that if I click anywhere on the scene all tabs collapse. I just want them to collapse when any of the tab options is selected except for the one selected which expands.

Can someone direct me in the proper direction, Red.
