/**
 * Next steps:
 *
 * Starting in Divi Areas Pro 3.2.0 you can customize the preview template
 * that is used to display the Divi Area search result on the front-end.
 *
 * To do this, you need a child theme. Then copy the file 
 * "wp-content/plugins/divi-areas-pro/includes/builder/templates/single-divi-area.php" 
 * into your child theme folder, e.g. "wp-content/themes/divi-child/single-divi-area.php"
 *
 * Now you can modify the "single-divi-area.php" template inside your 
 * child theme - just ensure to keep the line "dap_cpt_the_preview()"!
