el-tree 拖拽到其他地方，不拖拽到树上

<template><el-treeclass="filter-tree":data="treeData":props="defaultProps"node-key="id"draggable:allow-drop="allowDrop"@node-drag-end="handleDragEnd"ref="tree"></el-tree>
</template>

// 阻止el-tree默认拖拽
const allowDrop = (draggingNode: Node, dropNode: Node, type: AllowDropType) => {return false;
}// 拖拽
const handleDragEnd = (draggingNode: Node,dropNode: Node,dropType: NodeDropType,ev: DragEvents
) => {console.log('tree drag end:', dropNode && dropNode.label, dropType)
}
