Touch Issues

[SimeonC]

Hi there, thanks for the directives.

I've been having issues with touch devices not closing the dropdown on select, it works fine on desktop browsers but it seems touch doesn't propagate the click event so I fixed the issue with the following code. Sorry I don't have time to make a proper PR.

this.select = function (selected) {
  if (selected !== $scope.dropdownModel) {
    angular.copy(selected, $scope.dropdownModel);
  }
  $scope.dropdownOnchange({
    selected: selected
   });
  DropdownService.toggleActive($element);
};

$element.bind('click', function (event) {
  // handle select toggles above in the select function
  var target = angular.element(event.srcElement || event.target);
  while (target[0] !== $element[0]) {
    if (target.hasClass('dropdown-item')) return;
    target = target.parent();
  }
  event.stopPropagation();
  DropdownService.toggleActive($element);
});
