Is there a theme that allows visitors to make a selection of categories to narrow down the search of blogposts? My blog holds recipes and I'd like my visitors to be able to choose a recipe that is glutenfree, lactosefree and a maincourse for example... Now I have a category "glutenfree" but that holds recipes with lactose aswell, so we have to narrow down the search.
Hope my explanation is clear. Thanx for an answer!
The blog I need help with is judesdiner.wordpress.com.
