By using the DJ-Classifieds extension you can easily override the component view using selected themes or using your own. The theme can be used globally or only for selected categories.
DJ-Classifieds comes with two default Themes: "Default" and "Clean". When using templates from Joomla-Monster, you will also find other themes available that are relevant to the template you have installed.
Open the DJ-Classifieds component and go to "Options." Choose the "Views" tab.
The "Clean theme" you can enable using the first option - "Theme.". Choose from the list and click "Save."
