Hi Kenneth,
OS Property supports the "Theme" mechanism. You can create your own theme and use it for your OS Property system.
One "theme" includes 3 main layouts: properties listing, search result and property details. These layouts appear almost at front-end of component.
To manage "themes", you can go to backend > OS Property > Manage themes.
To get more details about this feature, you can read the documentation of OS Property
osproperty.ext4joomla.com/OS_Property_Instructions.pdf
Thanks
Dam
