}, {
  title: "Categories",

    key: "title",
    title: "Title",
  }
];

export default ({ attributes }) => (
  <array
    dataSource={attributes.dataSource}
    keyName="OtherMenuItem"
    title="otherMenuItem"
    ui="tableRoute"
    uiParams={{columns}}
  >
    <toolbar>
      <pagination />
    </toolbar>
    <Tabs>
      <string
        keyName="title"
        title="title"
        required
        layout="horizontal"
