How can you modify a Codeigniter default pagination to follow

----viewMore--- link style when loading for more record - AJAX way.

The thing is how do you make the div so auto expanding that like you handle a 10,000 record at a time.

Try this

Make two Hidden Input in view

<button type="button" onclick="loadmore()" value="loadmore" >Load More</button>
<input type="hidden" name="limit" id="limit" value="10"/>
<input type="hidden" name="offset" id="offset" value="20"/>

Ajax call

function loadmore(){
    $.ajax({
        url:your_controller/loadmore,
        data:{
          offset :$('#offset').val(),
          limit :$('#limit').val()
        },
        type:json, 
        success :function(data){
            $('#load-more').prepend(data.view)
            $('#offset').val(data.offset)
            $('#limit').val(data.limit)
        }
    })
}

In your controller call model

 function loadmore(){
      $limit = $this->input->get('limit');
      $offset = $this->input->get('offset');
      $this->load->model('yourmodel');
      $result  = $this->yourmodel->getdata($offset,$limit);
      $data['view'] = $result;
      $data['offset'] =$offset +10;
      $data['limit'] =$limit;
      echo json_encode($data);
    }

write query in model with offset and limit
