This code will replace <select multiple...> boxes with a readonly text input that shows all items selected.  When clicked, a modal will appear giving the user the ability to select items with check boxes.  In the page load function, just call setup_selection_popups().  The select elements should have a class of "replaceable", and of course the multiple attribute must be present.  Everything is contained in one javascript file, and a css file.  Bootstrap 4 uses jquery, so it must be present.  However, jquery is used only to show the modal.

// Based on Stripe's jquery.payment, offers a simple set of utilities
// for handling credit card numbers, expirations, and CVC/CVV2 codes
//
// cc_format_card_number(field)
// cc_format_card_expiry(field)
// cc_format_card_cvc(field)
//
//   "field" may be either the actual DOM element reference or a string
//   with the ID of the DOM element.  This will add event handlers to
//   the field to handle input.

  In this file, the fields can be set to "required", but that will
  cause issues.  Specifically, when someone clicks "Remove" the fields
  will be hidden and unless the "required" prop is set to false the form
  will not submit.  Also note that when showing this line if the object
  is marked_for_destruction? it should be hidden. The javascript below
  will handle both these issues.
-->
<tr class="line_item subform fields" id="line_item_<%= f.object.id %>">
  <td>
