How to put border over several checkboxes?

[chshersh]

I would like to draw a layout where I have several groups of checkboxes. To make visual representation of my TUI nicer, I would like to group checkboxes with the help of some border. So I want to draw something like below:

---Group 1---
| [ ] Foo 1 |
| [ ] Bar 1 |
-------------

---Group 2---
| [ ] Foo 2 |
| [ ] Bar 2 |
-------------

I see that @@= operator composes, but it can put only single FormFieldSet into the border:

brick/programs/FormDemo.hs

Lines 73 to 75 in 618b00a

	, label "Address" @@=
	B.borderWithLabel (str "Mailing") @@=
	editTextField address AddressField (Just 3)

Is there any way to group multiple checkboxes inside border?

The forms API isn't intended to support this kind of presentation, unfortunately. With care, though, you could do it with joinable borders, if it is really important to you to get this working. I wouldn't recommend that approach, though, because it's going to be a mess. In case it would help, though, here's a modified version of the bundled FormDemo.hs that does this for a pair of adjacent fields.
