Tabs separate content by heading and are an efficient way to organize data and avoid lots of scrolling. To use them, first add a "Tabs" container, and between the tags and add "Tab item"s. NB You can not put bullet points inside tabs.
The Tabs container has no settings. You just need to insert it on the page. The Tab item asks you to set the Tab title.
The following image shows how a Tabs container and set of Tab items will look on the page in edit mode.
