Reactice Builder

Before you start up you will need to create the builder shortcode from the wp-admin panel. Go to Dashboard > Reactive Builder > Add New

Step 1: Enter any title
Step 2: Select post type
Step 3: Select AJAX loading or not?
Step 4: Save

With this simple 4 step you will get the required shortcode for search page builder. This feature is available from version 2.0. So if you are a version 1.0 user you have to create your search page again.

Copy the shortcode and paste it to your page content area.
