This tutorial can be applied to any CMS section, we'll show you how to do it on a Map section as an example.
In your Map's section, a gradient effect is applied to your images by default.
It is possible to hide this gradient.
You must first purchase the Developer Plan to activate the JSON Edition.
This option is free with the Developer Plan subscription and can be purchased for an additional cost with the other plans.
If the JSON Edition is activated, the JSON tab appears at the top right of the right column of your back office.

8- Click "Ok"
