Expand Collapse Functionality on Left Vertical Navigation

Question

Hi,
I am trying to implement an expand/collapse functionality for subcommunities and their links in the left vertical navigation menu. My communities appear as horizontal tabs (as in the support center navigation). Once i have a community selected, the left navigation is rendered with all subcommunities and their links. If i now want to collapse/expand a specific subcommunity, how do i do it?
More specifically, how do i identify what subcommunity i clicked on the vertical nav, so that the next time i am rendering the display of the left nav, i can appropriately expand/collapse only that subcommunity.
regards
