Very possibly, can you provide a link and explain where you want it and we can advise :-)

I have seen that is possible to assign styles to a rows. It's just what i was looking for.
On there's any other way?
Many thanks again

In your custom field definition you can add a 'render class' - see screenshot below for demonstration

You can then set these styles for these elements in your template's custom CSS OR in the Custom CSS section of your EasyLayout layout at the bottom of the edit page.

OK.
I didn't know this feature. I'll try it.
Thankssssss!!!
