Hello!
We have an html attribute data-gjs-draggable:

      editor.BlockManager.add('columns', {
        label: "Column",
        category: "Layouts",
        content: `<table data-gjs-droppable="["tbody", "thead"]" data-gjs-draggable="[data-gjs-type=wrapper]" class="table-row">
          <tr>
            <td class="table-cell">
              <p>Text</p>
            </td>
          </tr>
          </table>`,
      });

data-gjs-draggable="[data-gjs-type=wrapper]":
You can put which component it can be draggable in it, wrapper is the body component in canva.
