Adding input dynamically using jquery the right way

Question

I have a simple form in which I want a user to be able to add inputs dynamically,

Here is what I have tried so far.

HTML form looks like this

HTML code for the above form

<form>
    <dvi class="container h-100">
        <div class="d-flex justify-content-center">
            <div class="card mt-5 col-md-12 animated bounceInDown myForm">
                <div class="card-header">
                    <h4>Bidders Information</h4>
                </div>
                <div class="card-body">
                    <form>
                        <div id="dynamic_container">
                            <div class="input-group">
                                <div class="input-group-prepend">
                                    <span class="input-group-text br-15"><i class="fa fa-tags"></i></span>
                                </div>
                                <input type="text" placeholder="Bidders Name" class="form-control" />
                            </div>
                            <div class="input-group mt-3" id="field">
                                <div class="input-group-prepend">
                                    <span class="input-group-text br-15"><i class="fa fa-tags"></i></span>
                                </div>
                                <input type="text" placeholder="atribute name" id="field1" class="form-control" />
                                <input type="text" placeholder="atribute value" id="field2" class="form-control" />
                                <a class="btn btn-secondary btn-sm" id="add_more_input">
                                    <i class="fa fa-minus-circle"></i> Add
                                </a>
                            </div>

                        </div>
                    </form>
                </div>
                <div class="card-footer">
                    <a class="btn btn-secondary btn-sm" id="add_more"><i class="fa fa-plus-circle"></i> Add</a>
                    <a class="btn btn-secondary btn-sm" id="remove_more"><i class="fa fa-trash-alt"></i> Remove</a>
                    <button class="btn btn-success btn-sm float-right submit_btn"><i class="fas fa-arrow-alt-circle-right"></i> Submit</button>
                </div>
            </div>
        </div>
    </dvi>
    </div>
    <div class="card-footer ml-auto mr-auto">
        <button type="submit" class="btn btn-primary">{{ __('Add Page') }}</button>
    </div>
    </div>
</form>

Here is jquery code for adding input dynamically

var next = 1;
$("#add_more_input").click(function(e) {
    e.preventDefault();
    var addto = "#field" + next;
    var addRemove = "#field" + (next);
    next = next + 1;
    var newIn = '<div class="input-group mt-3" id="field"><div class="input-group-prepend"><span class="input-group-text br-15"><i class="fa fa-tags"></i></span></div><input type="text" placeholder="atribute name" class="form-control" id="field' + next + '" name="field' + next + '"/>  <input type="text" placeholder="atribute value" class="form-control" id="field' + next + '" name="field' + next + '"/></div> ';

    var newInput = $(newIn);
    var removeBtn = '<a id="remove' + (next - 1) + '" class="btn btn-secondary btn-sm remove-me add_more_input"><i class="fa fa-minus-circle"></i> Add</a></div><div id="field';
    var removeButton = $(removeBtn);
    $(addto).after(newInput);

    $(addRemove).after(removeButton);
    $("#field" + next).attr('data-source', $(addto).attr('data-source'));
    $("#count").val(next);

    $('.remove-me').click(function(e) {
        e.preventDefault();
        var fieldNum = this.id.charAt(this.id.length - 1);
        var fieldID = "#field" + fieldNum;
        $(this).remove();
        $(fieldID).remove();
    });
});

Now when a user clicks button add input row I am getting the following

but the expected result should look like this

HERE is jsfiddle DEMO

You can use the clone function in jquery and change the cloned div id and then you can add the new div wherever you want example :

$('#cloneDiv').click(function(){

  var $div = $('div[id^="DIV_ID_to_clone"]:last');

  // Read the Number from that DIV's ID if you could add a number to your div id (i.e: 3 from "field_1")
  // And increment that number by 1
  var num = parseInt( $div.prop("id").match(/\d+/g), 10 ) +1;

  // Clone it and assign the new ID (i.e: from num 4 to ID "field_2")
  var $cloned= $div.clone().prop('id', 'field_'+num );

  // Finally insert $cloned wherever you want
  $div.after( $cloned.text('field_'+num) );

});
