Angularjs数据切换=下拉列表不使用选择选项

在我的代码中，我使用了简单的下拉绑定，带有使用ng repeat的选项，但当我绑定该选项时，它不会显示任何内容，因为javascript中可能启用了一些额外的类。我的正常代码是：

    <div class="col-md-6 col-sm-12">
     <label>Select Employee</label>

     <select class="form-control show tick" id="selectEmp" name="toEmployeeCode" required="" ng-model="toEmployeeCode">
     <option value="">Select Team Member</option>
         <option ng-repeat="x in AllEmployee" value="{{x.EmployeeCode}}">{{x.FirstName}} {{x.MiddleName}} {{x.LastName}}</option>
           </select>
          </div>

不要在

中使用

ng repeat

，它工作不正常。改为在select中使用

选择团队成员

选择团队成员

但它不显示链接
