My main wordpress menu is set up, but none of the drop downs are working. Any top level menu items with pages below them aren’t clickable. I’m not using any advanced options, just the standard wordpress menu. http://perthmodernquiltguild.com
You have added dropdown-header as title attribute for menu items which is completely unnecessary and is not linked to any Glyph Icon which is why this field is there in first place. Remove that title attribute and you will be ready to go.
