AngularJs 如何实现多级联动且最后一级下拉可以选择多个选项。请附上正确例子

Answer 1

<select ng-model="selectedDistrict" ng-change="selectedUnit=''" ng-options="district.name for district in districts" class="ng-valid ng-dirty"></select>

<select ng-model="selectedUnit" ng-change="selectedPosition=''" ng-options="unit.name for unit in selectedDistrict.units" class="ng-valid ng-dirty"></select>
这个是两级联动。如果要多选，建议你用插件isteven-multi-select。

Answer 2

AngularJs好像没有这么强大 没法实现
