I have a great number of categories and they make my site very long.
What I want to do is:
- Create some primary categories with letter names : A, B, C, D, E ... Z
- Make my current categories subcategories of those letters.
When someone wants to go to Movies, for example, he would click the M category and then all the sub-categories that start with M would expand.
Also, I see another problem in WordPress, when I make a category and I put a sub-category into it, the link would change from http://www.site.com/category/Movies to http://www.site.com/category/M/Movies.
