I am currently working on a Wordpress website that needs an advanced search adding to it.
I have three categories set up, each with a set amount of sub-categories, and then I'd like for a user to be able to select from three dropdown menus three different sub-categories.
So I'd have a set up like so:
I will create a post and add the post to a subcategory from each category, and then a user can search for a post that's in three specific subcategories.
For example, I'd like a user to be able to search for posts that are in cat1subcat1 AND cat2subcat1 AND cat3subcat1
I don't want there to be an actual search box for users to type in a query, I would just like the three dropdown menus.
Does anyone know if this is possible? I've looked at some plugins, but none seem to do this specifically.
Thanks in advance for any help.
EDITED TO ADD: This isn't a feature I want in a sidebar of the site. When a user goes to the homepage, the only thing they see on the page are the three dropdown menus. Another user suggested it's a filter, and whilst I'm aware that I can filter posts by category in a sidebar, this isn't what I need.
