===================
详细讲解（以下紧看文案和使用方式即可，非上面效果图的代码）
<ul class="projset-content">
<!--拖拽控件-->
<!--
handle:只有当鼠标移动到css为dargBtn类的元素上才能拖动
filter：设置了undraggable样式的元素不允许拖动
chosenClass:被选中目标的样式，你的自定义样式可能需要加!important才能生效，并把forceFallback属性设置成true
ghostClass：设置拖动元素的占位符类名（占位的样式）,你的自定义样式可能需要加!important才能生效，并把forceFallback属性设置成true
dragClass：拖动元素的样式，你的自定义样式可能需要加!important才能生效，并把forceFallback属性设置成true
fallbackClass：克隆的DOM元素的类名
draggable：指定哪些元素是可以被拖动的
-->

=====================
除此以外，想拖拽后直接拿到最后排序完之后的数组，可以使用下面的方法
onEnd_all() { console.log("this.cacheSelected:", this.cacheSelected); console.log("this.allCache:", this.sortList); console.log("this.itemList:", this.itemList); },
<draggable :group="groupName" v-model="sortList" @end="end" @start="start" @update="upd"
:forceFallback="true" dragClass="dragClass" :move="onMove" fallbackClass="fallbackClass"
chosenClass="chosenClass" ghostClass="ghostClass" filter=".undraggable">
上面所有的拖拽函数清空只用
@end="onEnd_all"
也就是
<draggable :group="groupName" v-model="sortList" @end="onEnd_all"
:forceFallback="true" dragClass="dragClass" fallbackClass="fallbackClass"
chosenClass="chosenClass" ghostClass="ghostClass" filter=".undraggable">
