OK - I think I understand this. You have a UI list which corresponds to variable #catandtag1. And you want this variable to be used to select the corresponding pull down menu 1. on the website. All you need to is: run javascript: mainCategorySelector("#catandtag1") I'll try and put together a quick example. Updated: Check the attached bot. Note this won't actually change the pulldown menu on the screen - but as far as Esty is concerned it has. etsy.ubot
