After you have made a Single Property template in the Fancify Template Builder, it is important that you customize your website, so that you can choose a template as default. Without this step, you should navigate to every single property page and manually change the template to the one of your choice.
To set one Single Property Template as the default layout of your single property pages, follow these steps:
Step 1: Create a Single Property Template (as discussed in the Single Property Builder documentation).
Step 2: Navigate to the Customizer by following this path: WordPress Admin > Appearance > Customize
Step 3: Click on WPL in the Customizer Panel.
Step 4: Click on WPL Properties
Step 5: Choose the template you would like to set as default from the drop down menu.
Step 6: Click on Publish at the bottom right of the Customizer Panel.
Once you publish, all single property pages that are set to default layouts, will change to the template you selected as default.
