關聯的Angular UI選擇

Question

我正在嘗試對ui-select進行分組，實際上每個ui-select選項都取決於前一個。 例如，我在第一個UI選擇中有一個級別列表，然后根據選擇的第一個ui選擇，將在第二個ui選擇上顯示一個地方編號列表。 那可能嗎？ 這是我的代碼，但是我還無法實現它:(

<div class="SumoSelect sumo_somename" tabindex="0" style="width:80%">
        <ui-select search-enabled=false ng-model="levelNumber.selected"
                        theme="bootstrap" append-to-body="true" on-select="getListPlacePerLevel(levelNumber.selected)">
                    <ui-select-match placeholder="">{{$select.selected.levelNumber}}</ui-select-match>
                    <ui-select-choices repeat="item in levels">
                    <span ng-bind="item.levelNumber"></span> </ui-select-choices> </ui-select>
    </div>
    <div class="SumoSelect sumo_somename" tabindex="0" style="width:80%; margin-top:20px;">
        <ui-select search-enabled=false ng-model="item.selected"
                        theme="bootstrap" append-to-body="true">
                    <ui-select-match placeholder="">{{$select.selected.item}}</ui-select-match>
                    <ui-select-choices repeat="item in levelNumber.selected.listPlaceNumber">
                    <span ng-bind="item"></span> </ui-select-choices> </ui-select>
    </div>

我的Json數據如下

[{"levelNumber":1,"listPlaceNumber":[1,2,3,4,6]},{"levelNumber":2,"listPlaceNumber":[2,4,6,7]},{"levelNumber":3,"listPlaceNumber":[11,12,13,14,16]}]
