    This showcases that you can use call func to achieve multiple layers of loop

  sections:
    - title: Demo
      log: yes

notes:
  goal:
    - demo how to do double layered loop
    - use call func to achieve that

          demo use both loopitem in same context
          the dvar parentLoopItem will map the value of parent loopitem
        dvars:
          - name: parentLoopItem
            value: '{{.loopitem}}'
        do:
          - name: print
            cmd: 'parent loop: {{.parentLoopItem}}, child loop: {{.loopitem}}'
        loop:
          - item1
          - item2
          - item3
