How to make that layout using Cursive

Guys, I'm using cursive library and I'm writing something similar to mc. I am struggling to create such layout:

I've asked the author but he seems to be inactive at the moment.
Could anyone please take a look and see if that's even possible?

Thank you

Looks like you need a Dialog with a couple of EditViews and Checkboxes

That is correct. But the lines that divide the dialog in three parts are the problematic parts
