How to make a select with any html code?

Question

Layout

Actually, there is such a layout:

A select with arbitrary content will be pushed into the radio, in turn there is a select with checkboxes. It is clear that it is not valid to do it purely on html, or rather not to do it in any way. Maybe someone has come across this, tell me the algorithm of actions or some jquery plugin :) Thanks in advance!

I will advise the classics: jQuery UI (select menu) custom renderer
