I can't access the site, i'm from France (ip blocking for France on your site...)
There could be 2 reasons for your issue:
- Problem with site template css style not well ajusted for dropdown list (you can test with Protostar template for the page, and see if it works)
- If not template, it could be a script or css conflict on the page... (with another extension installed...)
