Try like following snippet:

new Vue({
  el: '#demo',
  data() {
    return {
      positions: [{PositionId:1, PositionName:'ccc'}, {PositionId:2, PositionName:'ddd'}],
      departments: [{DepartmentId:1,DepartmentName: 'aaa'}, {DepartmentId:2,DepartmentName: 'bbb'}],
      isActivate: null,
    };
  },
  methods:{
    activateCbb(type) {
      if(this.isActivate === type) {
        this.isActivate = null
      } else {
        this.isActivate = type
      }
    },
  }
})

Vue.config.productionTip = false
Vue.config.devtools = false

.sl-activate {
  display: block;
}
.inactive {
  display: none;
}
