There are a few problems that I have with the Post Type Variable.
First, It looks like you can only setup 30 MAX attributes for the Variable Post Type. I believe it or not, have 33 that need to be used. If I select all 33 attributes and then link all variations, nothing happens. If I select 30, then I am then able to move forward.
Second, there is no styling for the Drop Down Menu. It is not syled like you have in your demo. Is there a way that I can style to match how yours looks. (links below)
Third, issue I am having is that the Mega Menu does not work correctly on this particular page. It is offset to the right for some reason. I am not sure if it is because of all of the information be generated from the drop down menu or not? All of my other pages work just like it should. This is for "Shop" in the menu.
Here are the links to compare:
Any help would be appreciated!
