Once a tag is no longer in use, it will automatically delete from your store:
Hi there, did you ever figure out how to delete the tags from showing up in the drop down "filter by"?
We can't seem to figure this out but have removed the tags from the items in the inventory side..
I have deleted some tags but some of the tags are still showing up in the filter and it's quite misleading, I have checked all products and those tags are related with no products, why are they still showing up? where I can delete them for good? thanks!
None of those answered the question of how to delete created tags from the drop-down. It's too easy and can cause a real problem having them in there.
Is there a way to remove a tag in the drop-down, I don't need to bulk remove them from my products list...but thanks!
