This is just an FYI to inform you that the “Container” element that’s located in the Columns section, doesn’t do anything. I first noticed because I have the “Container” element starred as a favorite, but this one is not starred like the others, so it is different in some way.
Then, upon trying to add this particular Container element into the CMS, nothing happens. I’ve tested in a number of projects within my account.
All other instances of the “Container” element work, including in my Favorites.
Here is a Loom screencast of unsuccessfully trying to input a Container with the button in “Columns”, and then finally successfully inserting one with the button in the “Elements”.
