Filter By Tags
Introduction
Follow this step to learn how to filter by tags.
Step 1: Add A New Filter
Add a New Filter and customize it. Set the Admin Filter Name as something like Tags, what you would like to filter as Tags, the Post Type as the Post Type that you would like to filter (e.g. Product, Posts, etc.) and the Filter Type as Select or Checkbox/Radio Buttons. This is enough to get the Tags filter working as long as you have set up the Archive Loop correctly.
