You can disable the dropdown functionality temporarily. This is a workaround.
Example with input field inside the drop-down "menu":
//for dropdown field not closing when clicking on inputfield
$(document).on('focus', 'input', function(e) {
// this attribute can be anything except "dropdown", you can leave it blank
$('#yourDropdownID').attr('data-toggle','off');
});
//for dropdown field back to normal when not on inputfield
$(document).on('focusout', 'input', function(e) {
$('#yourDropdownID').attr('data-toggle','dropdown');
});
This can be used on anything that is clickable and you can define individually what items clicked can close or not close the drop-down menu.
