component dialog - how do I wrap/group fields inside a box?
just to quickly explain the situation
I have a component dialog with lots of textfields.
granite/ui/components/coral/foundation/form/textfield
Because of usability issues, I want to group the related ones by enclosing them in sort sort of box like in the screenshot below.
I've already tried
granite/ui/components/coral/foundation/form/fieldsetbut the behavior is different.
Any ideas on how can I do it? Thank you.

This is a screenshot for a sample form from w3schools.

How can I do it?
