Tree Component

A tree component, to display hierarchical data.

Requirements

This component utilizes the Cylc TreeItem component, as well as Vuetify 1.5 components like VLayout, VFlex, etc.

Props

workflows

The main data structure. It is based on the response of the GraphQL query, but with a few modifications. In order to support recursion in the component, we need a fixed entry with the children nodes. Plus, in order to allow for customization based on the type of the node, it also requires a custom field __type.

• type: Array
• required: true
• example:

[
  {
    __type: 'workflow',
    id: 'user/workflow1',
    name: 'workflow1',
    status: 'running',
    children: [
      {
        __type: 'checkpoint',
        id: '20100101T0000Z',
        name: '20100101T0000Z',
        state: 'failed',
        children: [
          {
            __type: 'task',
            id: 'user/workflow1/20100101T0000Z/foo',
            name: 'foo',
            state: 'failed',

                id: 'user/workflow1/20100101T0000Z/foo/01',
                name: '#1',
