Result:

To have a dropdown for your own team copy over all of the content below. It might be needed to adjust a thing or two. Comments have been added throughout the code what must be changed.

Inspirational websites:

  • [http://javascript-array.com/scripts/simple_drop_down_menu/ Most basic dropdown menu, with no submenu's]
  • [http://jquery.com/ The javascript library used to add effects and optimise the dropdown]
  • [http://www.tyssendesign.com.au/articles/css/centering-a-dropdown-menu/ How to center a ul list effectively]

The dropdown has been created and developed by the KULeuven team.
