Add a section onto a new page. Then paste the following code into a Code block anywhere into that new section.
<div data-wm-plugin="tabs">
<button>Tab One</button>
<button>Tab Two</button>
</div>
Add as many button elements as you would like tabs.
Then add page sections beneath the section with your tab buttons. Each proceeding section will automatically be connected to each tab, in order, until there are no more buttons or sections.
