[web2py] form in modal

[Shawn Michaels]

Hi, I managed to get form in modal to work, but I have problem - when I 
submit form the form hides and there is still shadow background there. I'm 
working with latest bootstrap (4.3.1) right now (don't know if it's the 
reason).
response.js with form.errors shows the form again but with accepted it's 
unable to hide. I suppose it should work without response.js at all but 
without it the form hides but as I stated before there is still shadow 
background over page.

def news():
    form = SQLFORM.factory(
        Field('your_name', requires=IS_NOT_EMPTY()),
        Field('your_state',))
    
    if form.process().accepted:
        response.js = '(function($) {$("#news").modal("hide");}(jQuery));'
        response.flash = 'form accepted'
    elif form.errors:
        response.js = '(function($) {$("#news").modal("show");}(jQuery));'
        response.flash = 'form has errors'
    else:
        #response.js = target_response
        response.flash = 'please fill the form'
    return dict(form=form)

<!-- news.load -->
<button type="button" class="btn btn-primary" data-toggle="modal" 
data-target="#news">
  News
</button>
<div class="modal fade" id="news" tabindex="-1" role="dialog" 
aria-labelledby="newsLabel" aria-hidden="true">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="newsLabel">News</h5>
        <button type="button" class="close" data-dismiss="modal" 
aria-label="Close">
          <span aria-hidden="true">&times;</span>
        </button>
      </div>
      <div class="modal-body">
        {{=form}}
      </div>
    </div>
  </div>
</div>

<!-- index.html -->
{{extend 'layout.html'}}
{{=LOAD('default', 'news.load', ajax=True)}}

Is it possible to get forms in modal to work? If so, how, thanks.
