Nested Drag and Drop with react-beautiful-dnd

Question

I'm creating vertical nested drag and drop with react-beautiful-dnd. I have referred some answers in github

I have forked from sandbox and created new one for vertical nested drag and drop. When I change the inside DND, outside DND changes the values not inside DND.

CODE

 onDragEnd(result) {
    // dropped outside the list
    console.log("innner drag");
    if (!result.destination) {
      return;
    }

    const items = reorder(
      this.state.items,
      result.source.index,
      result.destination.index
    );

    this.setState({
      items
    });
  }

Answer 1

react-beautiful-dnd doesn't support nested drag-drop as of now and it's low priority item as per their roadmap. You need to handle everything on outer <DragDropContext onDragEnd={this.handleDragEnd}>. It doesn't give parent information by default in result object, so I have kept that information in child Droppable component. See the below demo if this works for you.

Edit: Refer below sandbox for a more generic code snippet where you will be able to apply nested drag-drop across parent container.

just give type to your outer and inner droppable, on drag end you have to check the type of your droppable,and reorder accordingly.

onDragEnd = ({ type, destination, source }) => {

    if (source && destination && type) {
        let parentId = source.droppableId;
        let srcIndex = source.index;
        let destIndex = destination.index;

        if (type == "Inner") {
            //method for reordering the order of the inner items
            reorderInner(parentId, srcIndex, destIndex)
        }
        else if (type == "Outer") {
            //method for reordering the order of parent items
            reorderOuter(srcIndex,destIndex)
        }
    }

};
