Good morning.

This is probably a very simple change but I'm stuck at the moment!

On our book library we have Genres (Categories) which have sub-categories for authors (manufacturers) so when you use the drop-down select a genre it then displays all the authors held within that genre. Selecting an author displays all their books.

We would like an option to simply browse all books regardless of the author by selecting a genre.

Any help would be greatly appreciated.

Thanks
