Hello, @gogimagogi
I would recommend you to create footer using a static block, then you will be able to edit the content using WPBakery Page Builder. For example, https://xstore.8theme.com/demos/2/organic01/ http://prntscr.com/msvvxp http://prntscr.com/msvw1q http://prntscr.com/msvw7q

Feel free to ask if you have any other questions.
