Questions / Comments:

There is a problem with the JS code for data-max. I assume it wants to limit the maximum fields to something but fails. To fix this, replace

var countFormGroup = .... ;

with

var countFormGroup = function ($form) {
return $form.siblings('.form-group').andSelf().length;
};

also, replace

var $lastFormGroupLast = ... ;

with

var $lastFormGroupLast = $multipleFormGroup.siblings('.form-group:last').andSelf();

Also, add the data-max attribute to the .mutliple-form-group.

Great Job !!
Unfortunately I don't know javascript but I have two questions:

1. how can I put a limit to the number of fields to be created. I would like to limit it to e.g. 8
2. Ist there is a possibilty to delete "used option" from selection ? E.g. If phone was already provided "phone" label shouldn't be available if I add new fields.

Thank you.

Thank you could't find any but I'm focusing on a different solution.
Just one question: What does this line says: <input type="hidden" class="input-group-select-val" name="contacts['type'][]" value="phone">
I'm trying to find out this line is acutually used for expected for design purpose .

Hi guys,
Recently I did use this snipped, thanks a lot for it!
I'd like to notice one issue in JS code, after line #16 you should paste

$formGroupClone.find('.input-group-select-val').text('phone');

Otherwise newly created inputs comes with empty type. Also I did my own parser for php side, it is very simple and I'd like to share it

I believe you can access the array to retrieve them. What framework/script do you use to retrieve input elements?
