我的意思是这样的：

{
  "persistent_menu":[
    {
      "locale":"default",
      "composer_input_disabled":false,
      "call_to_actions":[
        {
          "title": " bla",
          "type":"nested",
          "call_to_actions":[
            {
              "title":" bla",
              "type":"postback",
              "payload":"SeeCourses_PAYLOAD"
            },
            {
              "title":" bla",
              "type":"postback",
              "payload":"SeeMyCourses_PAYLOAD"
            },
        {
          "title":" bla",
          "type":"postback",
          "payload":"SearchForCourses_PAYLOAD"
        }
          ]
        },
        {
          "title":" bla",
          "type":"postback",
          "payload":"SessionsDateAndTimes_PAYLOAD"
        },
        {
          "title":"? bla",
          "type":"postback",
          "payload":"InsituteInfo_PAYLOAD"
        }
      ]
    },
    {
      "locale":"ar_AR",
      "composer_input_disabled":false,
      "call_to_actions":[
        {
          "type":"postback",
          "title":"Change Language",
          "payload":"Change Language"
        }
      ]
