Category buttons

[emily-dsl]

On each posts page there are a series of 3 categories assigned to each post. whether it is indoors/outdoors, the county/major city it is in and a broad keyword about the location e.g. park, museum etc.

Indoors and Outdoors are used as buttons and menu items within the website, which is great.

I would also like users to be able to click on Kent or Parks and get a list of Kent locations or Park locations as we current;y have with Indoors/Outdoors. However, with many many possibilities this would soon over populate the top menu. I would like these "lists" to exist but to be "hidden" until clicked through the post page.
