Let's say we have a field in our data collection with colors like #ffeeff and so on stored.
I want to be able to deep map that, let's say we have a box on our page and now I want to connect the property backGroundColor on that box to my dataset.
$w("#myElement").style.backgroundColor = "rgba(255,0,0,0.5)";
So I want to visually click the box and click the connection to Dataset and select Properties and then set dynamic data to a special property.
This could be colors, visibility like hide collapsed and more. Very useful feature I think.
