unlimited Link Categories or sub items

Hello All,

I would like to use the word press links admin section to allow my client to manage their own navigation, however, I have noticed that I can only have one tier of links. I would like to be able to make sub-links or sub-categories that would output nested list with unlimited sub list. I hope that made sense.

I want to give my client the ability to easily add navigation items to drop down menus. I don’t want to restrict the tiers of those menus.

I have been searching for a long time for a plugin or hack to incorporate this functionality. Any help would be greatly appreciated.

If I have to have this type of plugin custom created, I will definitely share it with all of you. Any suggestions or feedback would be great.
