Joomla (and Joomla 4) itself has the option to work with tabs in your content. This tutorial will explain how this works.

First: YES it is native Joomla, you do not need an external plugin for this to work. Go to EXTENSION/PLUGINS, and find the plugin CONTENT-PAGE BREAK

 

 

Make sure the plugin is enabled you can set the Presentation Style to your needs. Once this is the done you can simply go into your article and use the Page Break button below the editor.

If it does not work, it actually does, but then you miss some CSS to make it happen (only Joomla 3). Joomla 4: check example below. This is done with just Joomla!
