Hello 
I tried to use CMS Tabs attribute. I’ve added all 3 attributes to my elements, including the tab-link attribute on a div.
In a note of the finsweet documentation we can read that :
The element on which you add this attribute will be moved inside of the corresponding Tab Link . On the published site, it will only appear in the Tab Link element, and disappear from its original position in the List Item element — that now shows up in the Tab Pane element.
But if I go to the live demo of the attribute, we can see that the tab-link is both inside the menu and the pane. I have the same issue on my website.
Am I missing something ?
