<div class="row" id="dsf">
    <div class="col-md-2">
        <select name="p_name" class="form-control" id="p_name">
            <option value="">-Select Product-</option>
            @foreach($products as $product)
                <option value="{{$product->product_id}}">{{$product->name}}</option>
            @endforeach
        </select>
    </div>
    <div class="col-md-2">
        <input type="text" name="p_code" id="p_code" class="form-control" readonly="">
    </div>
    <div class="col-md-2">
        <input type="text" name="unit_pctn" id="unit_pctn" class="form-control" readonly="">
    </div>
    <div class="col-md-2">
        <input type="text" name="u_price" id="u_price" class="form-control" readonly="">

    </div>
    <div class="col-md-1">
        <input type="text" name="pcs" id ="pcs" class="form-control">

</div>

Here is my jquery part.

$(document).ready(function(){
    $("#addrow").click(function(){
        $("#dsf").append();
    });
});

if you want to append data after div then use this code

$(document).ready(function(){
        $("#addrow").click(function(){
            var content = $("#dsf").html();
            $('#addrow').append(content);
        });
    });

this is demo code for test

  $(document).ready(function(){ $("#addrow").click(function(){ var content = $("#dsf").html(); $('#addrow').append(content); }); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="row" id="dsf"> <div class="col-md-2"> <input type="text" name="p_code" id="p_code" class="form-control" readonly=""> </div> <div class="col-md-2"> <input type="text" name="unit_pctn" id="unit_pctn" class="form-control" readonly=""> </div> <div class="col-md-2"> <input type="text" name="u_price" id="u_price" class="form-control" readonly=""> </div> <div class="col-md-1"> <input type="text" name="ctn" id="ctn" class="form-control"> </div> <div class="col-md-1"> <input type="text" name="pcs" id ="pcs" class="form-control"> </div> <div class="col-md-2"> <input type="text" name="t_amt" id="t_amt" class="form-control"> </div> </div> <div id="addrow">Click</div> 

or you can append after addrow

 $(document).ready(function(){ $("#addrow").click(function(){ var content = $("#dsf").html(); $( content ).insertBefore( "#addrow" ); }); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="row" id="dsf"> <div class="col-md-2"> <input type="text" name="p_code" id="p_code" class="form-control" readonly=""> </div> <div class="col-md-2"> <input type="text" name="unit_pctn" id="unit_pctn" class="form-control" readonly=""> </div> <div class="col-md-2"> <input type="text" name="u_price" id="u_price" class="form-control" readonly=""> </div> <div class="col-md-1"> <input type="text" name="ctn" id="ctn" class="form-control"> </div> <div class="col-md-1"> <input type="text" name="pcs" id ="pcs" class="form-control"> </div> <div class="col-md-2"> <input type="text" name="t_amt" id="t_amt" class="form-control"> </div> </div> <div id="addrow">Click</div>
