I have a archive template for post categories. I would like to know if is possible using query builder, extract the most used post tags for post of current category
This Pro tutorial provides the steps to set up a Terms query loop in Bricks for tags and order the results by the tag count for the posts in the current category when viewing category archive pages.
Step 1
Edit the template (create, if not existing) that applies to your category archives with Bricks.
