Hello, So on my page when i click All E-Liquids it opens the drop down menu instead of going to All E-Liquids page which i have linked and worked before i changed over to Online Store 2.0. (this happens to all main menu headings that have drop down option)
It appears that your theme is setup to have that as a different element than a link, specifically meant to trigger the toggling of the drop-down.
My recommendation would be to include those link as the first one in the list of the drop-down as that would be easier and quicker than modifying the navigation code to have it work as a way of navigating to the link item’s associated page.
Hope that helps!
