Turn your Wordpress post categories into a search powerhouse! This plugin gives you the ability to provide your users with a widget full of dropdowns based upon parent categories and their sub-categories.

Multiple subcategories spanning multiple parent categories (though multiple categories inside a single parent cannot be chosen) are chosen and intelligently filter your posts.

Sample Application:

Real Estate - set up parent categories such as 'Bedrooms', 'Bathrooms', 'Price Range', etc. Then put sub-categories beneath them.

Create a new post and tick all applicable sub-categories. Users should now be able to search for your post under all those categories!

Features:

• Inclusive category search
• Exclusive category search
• Automatically checks for the 'uncategorized' category and hides it

List of possible future features:

• Admin page for full customization of widget behaviour
• More than one sub-level!!
• Ability to save the current view for bookmarking later (full URL would be in the address bar as well possibly - also unknown if it will work with permalinks)

Please be aware that I'll only be updating this if I need to or if I'm paid to. Feel free to come on board and contribute!
