We have used Bootstrap's button-dropdown component to create a SELECT TAG like experience. User can click the dropdown and choose any option and the same value is instantly shown inside button (accessible via Mouse as well as keyboard)

Step 1: Click on single line option value inside dropdown.

Step 2: Now click on some multiple lines option value inside dropdown.

Step 3: Now once again click on some single line option value inside dropdown.

Issue: After step 3 the dropdown list(i.e., ul) is not disappearing.

Expected Result: After step 3 the dropdown list(i.e., ul) should disappear on every selection of options(both on mouse click and keyboard usage).

Please ignore caret and design related minor bugs

Why won't you close the list manually?

Replace this line:

$(this).parents('.dropdown-menu').find('li').removeClass('active');

With this:

$(this).parents('.dropdown-menu').parent().removeClass('open').end().find('li').removeClass('active');

This would be the end code:

$('.btn-group').on('focus', '.dropdown-menu li', function() {
    $(this).siblings('.active').removeClass('active').end().addClass('active');

   //Displays selected text on dropdown-toggle button
   $(this).closest(":has(button)").find('button').html('<div class="dropDownSelected">' + $(this).children('a').html() + '</div>' + '<span class="caret" style="float:right;"></span>');
}).on('click mouseup', '.dropdown-menu li a', function() {
   $(this).parents('.dropdown-menu').parent().removeClass('open');
});

.btn-group,
.dropdown-menu {
  max-width: 150px;
}
.dropdown-menu li a {
  white-space: normal!important;
  ;
}
.dropDownSelected {
  white-space: normal;
  margin-right: 22px !important;
}
