You can enter the {tab} tags directly into your content. However, to save time typing and remembering what the exact syntax is, Tabs comes with a handy editor button.

You can use this editor button (located below the text input area) to easily place the Tabs tag block in your article (or other editor fields).

After inserting the example code, you can change it in your editor to whatever you desire.

You can customize the default example code in the Tabs system plugin settings.
