First of all, great plugin! It works fantastic.
The only question i have is:
Is it possible to automatic generate the options of a meta key?
I have 300 posts about different products. Every post has a custom field with a meta key "brand". There are 34 different brands in the database.
It would be awesome if i can say by the options (drop-down menu content) of the meta key "brand":
"All brands in the meta key brand". So the dropdown menu will be:
Brand 3.. etc.
Instead of typing all brands by myself ( brand 1 | brand 2 | brand 3 | etc.)
Thanks in advance!
