因專案需要，區域需要實現效果中的結果，select的option無法自定義，故通過自定義的div來實現該區域框。具體程式碼如下：

html

<div class="service-list">
    <div class="col-xs-12 overflow marginB20 no-padding text-bg-write">
        <div class="al-common-tabs">
            <div class="al-tabs-choose" ng-click="choose()">
                <span class="font-bolder" style="pointer-events: none;">當前單位：</span>
                <span class="text-0 cursorPointer" ng-show="newReqInfo.cityName==null">{{newReqInfo.provinceName}}</span>
                <span class="text-0 cursorPointer" ng-show="newReqInfo.cityName!=null">{{newReqInfo.cityName}}</span>
                <span class="al-tabs-arrow"></span>
            </div>
        </div>
    </div>
    <!--區域框-->
    <div class="onlineSearchArea" ng-if="SearchArea">
        <div class="col-xs-12 no-padding">
            <div class="col-xs-11 no-left-padding text-blue text-font16">選擇單位</div>
            <div class="topArrow" ng-click="choose('0')"></div>
        </div>
        <div class="col-xs-12 areaShow">
            <div class="col-xs-3 no-left-padding marginT10" ng-click="againProvince()">
                <span class="cursorPointer" ng-show="newReqInfo.nextProvinceName==null || newReqInfo.nextProvinceName=='' || newReqInfo.nextProvinceName=='undefined'">請選擇</span>
                <span>{{newReqInfo.nextProvinceName}}</span>
            </div>
            <div class="col-xs-4 no-padding marginT10" ng-click="againCity()">
                <span class="cursorPointer" ng-show="showPower">請選擇</span>
                {{newReqInfo.nextCityName}}
            </div>
            <div class="col-xs-3 no-padding">
                <!--預留第三級區域-->
            </div>
            <button class="col-xs-2 btn btn-primary" ng-click="choose('1')">確定</button>
        </div>
        <div class="col-xs-12 no-padding marginT10">
            <div class="col-xs-3 marginT10 padding2" ng-repeat="p in provinces" ng-show="!showCity || newReqInfo.nextProvince=='nw'">
                <div class="area-set text-bg-write" ng-click="changeProvince(p)">{{p.name}}</div>
            </div>

            <div class="col-xs-3 marginT10 padding2" ng-repeat="c in cities" ng-show="showCity">
                <div class="area-set text-bg-write" ng-click="changeCity(c)">{{c.name}}</div>
            </div>
        </div>
    </div>
</div>

 css

/*適用於單個tab*/
.al-common-tabs,.structure-common-tab,.system-common-tabs{
    width: 100%;
    overflow: hidden;
}
.al-common-tabs>span{
    padding: 0 15px;
    height: 50px;
    line-height: 50px;
    font-size: 16px;
    display: inline-block;
    margin: 0 10px;
    cursor: pointer;
}
.al-common-tabs>span:first-child{
    margin-left: 0 !important;
    cursor: default;
}
.al-tabs-choose{
    display: inline-block;
    float: right;
    line-height: 50px;
    margin-right: 20px;
    color: #999;
}
.al-tabs-arrow{
    width:0px;
    height:0px;
    border: 6.6px solid transparent;
    border-top-color: #999;
    content:'';
    display: inline-block;
    vertical-align: middle;
    cursor: pointer;
}
.onlineSearchArea{
    position: absolute;
    top: 70px;
    right: 5px;
    display: block !important;
    width: 520px !important;
    background: #F2F2F2;
    text-indent: 5px;
    z-index: 10;
