To make it more apparent which related columns need to be updated in an IG application, I'd like to color the background of the columns. So I can document for the user, in situation A, enter the blue columns, for situation B, enter the green columns... The colors don't need to be dynamic--the columns will always be the same color.
I see in the app builder, on the grid columns under 'Appearance', there is 'CSS Classes'; also, under 'Advanced' there is 'CSS Classes' and 'Custom Attributes'...but nowhere can I find an explanation how to use those attributes. Is there some documentation that explains and maybe gives examples of how these can be used?
