Drupal: how can I add text areas to my menus?

how can I add text areas to my menus with Drupal ?

For example see lancelmaat.nl Menu > Contact... I would like to put some t开发者_高级运维ext to a submenu and edit it from backend.

Thanks

I think you're have the wrong approach.

Instead, make those boxes blocks, have them in a left sidebar and hide them with JS. When the menu item is hovered, show it.

It's rather easy to achieve that using jQuery, which comes bundled with Drupal.
