This is the documentation for the Joomla 3 version of Advanced Template Manager.
There is currently no Joomla 4 version of Advanced Template Manager.

Advanced Template Manager is a Joomla! administrator component (combined with a system plugin) that enhances the way your template manager works.

With Joomla! you can normally only assign template styles to certain menu items.

With Advanced Template Manager you have the possibility to assign your site template styles to just about anything you want, including Joomla! Content, Users, Components, Devices and much more, giving you full control over your Joomla templates. In this tutorial we will describe all the assignment options available.

Once Advanced Template Manager is installed, the core Joomla template manager will be replaced with the Advanced Template Manager. The Templates menu link under Extensions will no longer point to option=com_templates but to option=com_advancedtemplates.

Advanced Template Manager also offers a few extra features to improve the template manager, like the ability to tag template styles with colours.
