    [actions]="actions">
</ngx-tree-dnd-container> 

nestedLists = [
  {
    title: 'Item 1',
    children: []
  },
  {
    title: 'Item 2',
    children: [
      {
        title: 'Item 2a',
        children: []
      },
      {
        title: 'Item 2b',
        children: []
      },
      {
        title: 'Item 2c',
        children: []
      }
    ]
  },
  {
    title: 'Item 3',
    children: [

      {
        title: 'Item 3c',
        children: []
      }
    ]
  }
];

actions = [
    {
      // action按钮material icon
      icon: 'remove_red_eye',
      /* 点击action按钮的回调函数 */
      callback: (model) => {
        /* model为当前actions所在item的model */
        /* do something */
      }
    },
    {

      callback: (model) => {}
    },
    {
      icon: 'delete',
