[ic] tree-menu component for IC 4.9

[interchange-users@icdevgroup.org (Rene Hertell)]

Hi,

Does anyone have a component that would work with the menu-editor in the
recent admin UI?

What I'm trying to build is a menu that would be built with the menu editor,
but it would show only the sub pages if you are on the parent page. All
other submenus would be hidden. The reason why I want this is that I have
quite much sub pages, and my main-menu would be too large if all would be
visible at the same time.

This is how the complete menu structure would look like:
Main
Page1
  Subpage1.1
  Subpage1.2
Page2
  Subpage2.1
  Subpage2.2
    SubSubpage2.2.1
    SubSubpage2.2.2
  Subpage3.2
Page3
  Subpage3.1
  Subpage3.2


Regards,

         Rene
