is it possible to drag the entire parent div in to child div. Dragula jQuery

Question

I created an HTML page with Dragula jQuery plugin. in this page there is 2 parent-div with peach color and each parent-div includes a child-div with blue color. is it possible to drag the entire parent-div in to another child-div. Currently the parent div not moving inside to a child div. looking for a solution.

[jsfiddle](https://jsfiddle.net/unni2003pj/2h5Lks0d/18/)

in this fiddle the parent-div and child-div are adding dynamically by button click.

JS:

// item drag and drop

// Initialize Dragula on the container
var dragulaContainer = [].slice.apply(document.querySelectorAll('.bloc'));
var drake;

function itemDrag() {
    drake = dragula([].slice.apply(document.querySelectorAll('.bloc')), {
        direction: 'horizontal'
    });
}

function destroyitemDrag() {
    drake.destroy();
}

function dragulaInt() {
    dragula([document.querySelector('.container')], {
        moves: function(el, container, handle) {
        return !handle.classList.contains('bloc--inner');
        }
    }); 
}

(function() {
    
    dragulaInt()
    //itemDrag();
})();
  
// Add Column
  
var i=0;
var j=0;

let newColNode = null;

function addRow() {    
    const row = document.createElement('div');
    row.className = 'bloc';
    row.id = "b" + ++i;
    document.getElementById('contentBox').append(row);
    itemDrag()

    row.addEventListener('click', function (event) {
        console.log(newColNode)
        console.log(row)
        if(newColNode != null ){
           
            destroyitemDrag()
            itemDrag()
            
        }
        row.appendChild(newColNode);        
        newColNode = null
    });
}
  
// Column Addition

function addCol() {
    const col = document.createElement('div');
    col.className = 'bloc--inner';
    col.id = "c" + ++j;
    col.textContent = `Column ${j}`;
    newColNode = col;
}
