Adding a tab menu can be good for when you have sub-subjects to your main subject, along with information or other content you wish to add to each tab. You can have multiple smaller subjects which appear as tabs and when the user clicks these tabs they will then show the relevant information inputted.
To do this, simply click the add button, then go into the Tabs area then click and drag the tab menu you wish to use. Once you have done this, you can then change the titles of the tabs, add content to each tab and even add or delete tabs. You can also change more settings through the configure tab depending on what is selected.
