Hi @mnmdesign, welcome to Webflow and to the Community Need Help pages 
You can setup an interaction on your list items to target some other element with a named class.
For more information on our interactions, check out http://interactions.webflow.com/.
If you need help with your site, could you update your post with some more information so we can help you faster? Things like your read-only link, and screenshots of the elements in question really speed things up.
Posting guidelines can be found here: Posting Guidelines for the Design Help Category - General - Forum | Webflow
Thanks in advance!
Cheers,
Dave
