I am doing this myself, and as you can tell, I am not sure of the correct names for what I am doing. BUT I did take a picture :) (I even had to Google how to take a screenshot!)
I gave all of my jewelry pieces a few tags each but I still have other random tags in the drop down search bar from when I brought them all over from my Etsy shop. Where do I delete these and just have that drop down menu with the simple tags I gave them? Like, necklace, earrings, cat, pig, etc.
