This is a simple Moodle filter which creates tabs in textfields.

First, activate the filter_tabs plugin in Site Administration -> Plugins -> Filters -> Manage filters

To create tabs in textfields where the filter is activated, simply use the following syntax:

{%:Tab title}Tab text{%}

Example

The following placeholders in a textfield:

{%:First tab}Some text{%}
{%:Second tab}Another text{%}

will produce this tab group:

+-------------+------------------+
| First tab | Second tab |
+---------------------------------+
| Some text                      |
|                                         |
+---------------------------------+

Bootstrap 4, Bootstrap 2 and YUI theme styles are supported.
