Joomla Language Bootstrap Dropdown with Flags

To replace the regular Joomla dropdown with a nice Bootstrap dropdown including flags (flag icons), just copy the following code in a file called /html/mod_languages/default.php inside your template folder.

In your module config for the language module, set "use dropdown" and "use icons" on true.

/yourTemplate/html/mod_languages/default.php

What is Joomla?

Joomla is a content management system for creating websites. As an open source project, Joomla is not only free, but is also constantly being developed by the community. The functions of Joomla can be extended as needed by modules and plugins and is therefore suitable for websites whose content changes frequently or is constantly expanded, such as blogs or online stores.

You can find more information about individual and responsive web development on our website or in a personal consultation.
