Deep nested list

[elvonkh]

I am using muuri-react and I want to make deep nested sortable list like in the image below I am using following code to generate nested list

import { MuuriComponent } from "muuri-react";
import React, { useCallback, useEffect, useState } from "react";
import CollectionItem from "./CollectionItem";
import { useGrid } from "muuri-react";

const sortedColl = [
  {
    id: "1db3cf0f-1705-4d24-a279-368d9ceb3a89",
    title: "New",
    children: [
      {
        id: "f653da27-7cba-4a94-9f3e-d08988d87348",
        title: "Dresses",
      },
      {
        id: "cce17318-21e6-42fa-9dc2-f60affd22e0a",
        title: "Dresses",
        children: [
          {
            id: "3f445f24-1000-415e-93f5-f59db4985dc2",
            title: "Dresses",
            children: [
              {
                id: "7510d247-5774-4bbc-8094-67ab5c530a16",
                title: "Clothing",
              },
            ],
          },
        ],
      },
    ],
  },
  {
    id: "91f27837-e17d-4064-96f6-51ff1aa8facb",
    title: "New",
  },

  {
    id: "3f445f24-1000-415e-93f5-f59db4985dc2",
    title: "Dresses",
  },
];
const coll =  [

  {
    id: "3f445f24-1000-415e-93f5-f59db4985dc2",
    title: "Dresses",
  },
];

function useSend(setItems, collections) {
  return useCallback(
    ({ key, fromId, toId, fromIndex, toIndex }) => {
      const blockPathTo = getBlockPath(toId);
      const blockPathFrom = getBlockPath(fromId);

          if (blockPathTo?.length === 0) {
            console.log('Block path is empty')
            tempList.splice(toIndex, 0, item);
          } else {

          }
          // const newList = addItemRecursively(currentList, blockPathTo, toIndex, item)
          return tempList;
        });
        // const item = collections.find(
        //   (collectionItem) => collectionItem.id === key
        // );

@elvonkh , hi, does muuri-react work with latest react versions(17)? https://github.com/Paol-imi/muuri-react/issues/50 https://github.com/Paol-imi/muuri-react/issues/59

or do you use fork version of it? https://github.com/adamerose/muuri-react btwn, your example looks similar with dndkit examples - https://5fc05e08a4a65d0021ae0bf2-gngonedmxi.chromatic.com/?path=/story/examples-tree-sortable--all-features

Hello! Sorry for being a little off topic, but I had a similar task to make a nested drag and drop navigation menu and tried many DnD packages like DnDKit, react-beautiful-dnd and etc...

I found a solution using a package called "atlaskit/tree". It required some tweaks to data structure, but in the end it solved this problem for me perfectly. The documentation is not the best so I recommend reading source code on the bitbucket

Docs and examples: https://atlaskit.atlassian.com/packages/confluence/tree BitBucket: https://bitbucket.org/atlassian/atlaskit-mk-2/src/master/packages/core/tree/src/
