Drag & Drop

[Farnsi]

Tried to replace the jQuery Drag & Drop with a vanilla version, but the mousedown event of parent .ts-control prevent the drag event-handler.

With SortableJS it would work perfect, but the mousedown event prevent it.

Any idea how to get around this?

Here is my hacky solution

dnd.plugin.js

import Sortable from 'sortablejs'

export default function DragAndDropPlugin() {
  if (this.settings.mode !== 'multi') {
    return
  }

  // stop propagation of re-rendered items
  this.hook('after', 'render', () => {
    if (this.control) {
      const items = this.control.querySelectorAll('[data-value]')

      items.forEach((item) => {
        item.addEventListener('mousedown', (e) => {
          e.stopPropagation()
        })
      })
    }
  })

  this.on('initialize', () => {
    new Sortable(this.control, {
      draggable: '[data-value]',
      filter: 'input',
      // animation: 150,
      // direction: 'horizontal', // to restrict to horizontal movement
      onEnd: () => {
        const values = this.control.querySelectorAll('[data-value]').map(
          (item) => item.dataset.value,
        )
        this.setValue(values)
      },
    })
  })
}

Select.jsx

import TomSelect from 'tom-select'
import { onMount, splitProps } from 'solid-js'

import { DragAndDropPlugin } from './dnd.plugin.js'

TomSelect.define('drag_drop', DragAndDropPlugin)

const Select = (props) => {
  let [local, rest] = splitProps(props, [
    // remove from rest (select onChange will not fired, instead it instance values)
    'onChange',
  ])

  let select

  onMount(() => {
    const instance = new TomSelect(select, {
      plugins:['drag_drop']
    })

    instance.on('change', local.onChange)
  })

  return (
    <select ref={select} onChange={(e) => e.preventDefault()} {...rest} />
  )
}

export default Select

You can implement some simple D&D with vanilla dom drag-Events, without sortablejs, but this feels like re-inventing the wheel.
sortablejs has nice animation and movement response included.

I'v just realised that recent version of TS does not require jQuery anymore 🥇
