I'm creating a directory using Gravity forms. I've set up conditional fields which allow a company in the directory to choose 3 top level categories, and then each of those displays checkboxes for sub-categories.
I'm not using WP native categories, but GF conditional fields.
My question is, I would like to display a page where I list all top level categories, and if a user clicks on a category, "computers & internet" for example is a top level category with 6 sub-categories within it. Then if I click "computers & internet", I would load a page that lists the 6 sub-categories. Is there any way to easily generate this already available? The way my fields are stored in the database seems like iterating through it to located top level categories and sub-level categories could be a nightmare.
