Vue.js Components For Draggable Lists – vddl

Vue components for modifying lists with the HTML5 drag & drop API.

💥Warning💥

• 1. Don't set index to the :key, it will cause dragging confusion.

<vddl-list :list="list">     <vddl-draggable class="panel__body--item"        v-for="(item, index) in list"        :key="item.id" // It's best to use a unique id. Remember, don't use 'index'.       ...       >       {{item.label}}     </vddl-draggable> </vddl-list>

• 2. "[Vue warn]: Duplicate keys detected: 'A-1'. This may cause an update error. "

Why is this wrong? Because in Vue.js v2.5.0 version, The nextTick's implementation has changed, specific can see here. The reason for throwing this error is that when the element is dropped onto the list, a duplicate object is inserted into the array. Now I think this can be done for you. Add a drop event to the vddl-list and add a moved event to the vddl-draggable. Then you need to splice the array manually. See the demo source code
