Question

Property.attachSchema(new SimpleSchema({
  'LGA': {
    label: "L.G.A",
    type: String,
    allowedValues:
    ["Aba","Oha", "Enu"],
    autoform: {
        afFieldInput: {
          firstOption: "(Pls, Select the L.G.A)"
        }
    }
  }
,
'Town': {
  label: "Town",
  type: String,
  allowedValues:
  ["Abakpa","Ewula", "Ezeoka", "Ubu","Echa", "Onu" ,"Eke", "Afor"],
  autoform: {
    afFieldInput: {
      firstOption: "(Pls, Select the Ward)"
    }
    }
  }

});

我有上面的架构，我使用quickForm来实现这个架构。＆＃34; Abakpa＆＃34;，＆＃34; Ewula＆＃34;，＆＃34; Ezeoka＆＃34;是＆＃34; Aba＆＃34; LGA＆＃34; Ubu＆＃34;，＆＃34; Echa＆＃34;，＆＃34; Onu＆＃34;是＆＃34; Oha＆＃34; LGA和＆＃34; Eke＆＃34;，＆＃34; Afor＆＃34;属于＆＃34; Enu＆＃34; LGA。这只是为了说明，因为列表非常多。我想要一个如果＆＃34; Aba＆＃34;如果选择了，则可用于城镇选择字段的选项将是＆＃34; Abakpa＆＃34;，＆＃34; Ewula＆＃34;，＆＃34; Ezeoka＆＃34;。如果选择了Oha，那么＆＃34; Ubu＆＃34;，＆＃34; Echa＆＃34;，＆＃34; Onu＆＃34;将是Town架构中的下一个选项等。请问我该如何实现？谢谢。
