Joomla 4 text filters can be used to allow or limit what HTML tags or attributes groups can use within the text editors. Joomla includes some default filter settings that are typically adequate for most situations. But, there may be times when you want to block or allow additional HTML tags or attributes.
For example, you may have discovered that a specific tag does not work well with your CSS and you want to block people from using it.
This guide will explain how to use Joomla Text Filters to limit or allow HTML tags and attributes in Joomla.
Setting Joomla 4 Text Filters
- Login to the Joomla Admin Panel.
- Click System then Global Configuration.
- Click the Text Filters tab.
You will then see a list of all the Filter Groups you can modify the setting for. Default groups are: Public, Guest, Manager, Administrator, Registered, Author, Editor, Publisher, and Super Users.
- Click the drop-down box under Filter Type to choose your preferred filter option, then fill in the Filter Tags and Filter Attributes if needed. Below is a description of the available options. Click the Save & Close button when you are done.
