We have the Hooks feature in our theme. With the help of this, you can add additional sections on the homepage before/after to any of the existing sections.
In the Wp-admin panel, Go to Appearance >> Innofit Hooks
You can add any type of content block like HTML markup, shortcodes and even a PHP snippet before or after any of the sections.
Here you can see how to add the custom content after slider and before the service section.
