There are two ways to build your own single listing template in Real Estate 7:
First, and recommended is with Elementor Pro and its Theme Builder, it gives you complete control of your design, all drag and drop without touching a line of code or CSS. It’s very easy to use and with our 30+ single listing modules for it, your design can be realized quickly, and easily. This also allows for conditional usage perfect when using our IDX, you can create specialized templates based on conditions say for “Pocket Listings” or “Exclusives” that you’d like to break out of the mold and showcase for prospective buyers — or provide as a distinctive upsell marketing service for your sellers.
Second, is by copying single-listings.php along with any of its 50+ includes depending on what you’d like to modify to your child theme and getting into the code directly. This option also allows you complete control, but requires a skilled knowledge of PHP, CSS & WordPress functionality, and is very time-consuming especially in the matter of testing and making sure your designs work well on all devices, from desktop to mobile.
