Sidebar
The Sidebar module gives you the ability to insert any of your WordPress sidebars into your layouts.
The widgets in the sidebar can be configured by going to Appearance > Widgets in the WordPress admin panel.
The Beaver Builder Theme has only one sidebar, called the Primary Sidebar. If you want to create a different sidebar or which widgets appear there, you must use a plugin or write code.
There are all the usual Advanced tab settings for margins, visibility, animations, and advanced HTML settings.
