It's possible to trigger click on form view's button with the help
of the "barcode_trigger" attributes. However, we don't want to be
able to execute clicks on items that aren't clickable by the user.
That's why we wrote the following condition: if the elem is visible
OR is a child of a .dropdown-menu, we trigger the click.
The second condition was always true since we used the jquery's
parent function which return an empty list when no result, and
an empty list is truthy.
