Booxter itself doesn’t bring any new post type, template or custom template once installed.
By default Booxter finds all the present post types, custom post types and custom templates as potential subjects. You just need to select which one (or more) fits best to your needs.
Alternatively, you can download Booxter Property plugin for free. It allows you to create categorised Property custom post type and works like a charm with Booxter – identically to what can be seen on this demo site.
Both, Booxter and Booxter Property will work with any theme. Of course, there’s a chance you’ll have to style up a bit these plugins’ front-end in order to make them match you theme’s design, but that’s just how things work.
