Hi Experts,

I am newbie to Angular and have a requirement to show the content based on dropdown value in Angular.I have following dropdown  values

None: show no content
Name: Show "Name" content only
Address:Show "Address" content only
All: Show both "Name" and "Address" contents.

I have below code developed in Visual Studio editor which is  working fine (UI screenshots attached ) using Angular,Bootstrap and HTML5.

I need sample working code for my requirement.

<div class="container" >

  <div style="padding:50px;" ng-controller="samplecontroller">

 <div class="row">
     <label class="col-lg-2">
         Status</label>
     <div class="col-lg-5">
         <select class="input-sm">
             
             <option selected value="none">None</option>
             <option value="name">Name</option>
             <option value="address">Address</option>
             <option value="all">All</option>
         </select>
     </div>
 </div>
 </br>
    
  <div class="row">
         <label class="col-lg-2">
             Name</label>
         <div class="col-lg-5">
             <p class="form-group">
                 {{name}}</p>
         </div>

     </div>
 </br>
     
     <div class="row">
                <label class="col-lg-2">
                     Address</label>
                 <div class="col-lg-5">
                    <p class="form-group">
                        {{address}}</p>
                  </div>

       </div>

   </div>

 </div>

Open in new window


<script type="text/javascript">
        function samplecontroller($scope) {
            $scope.name = "FOO";
            $scope.address = "ADDRESS1";

Thank you. I need "text" values in dropdown so I have changed below code from s.value to s.text

 <select class="input-sm" ng-model="state" ng-options="s.text for s in status"></select>

Open in new window


In reality, I have 6 dropdown values and 5 divs in a page layout and based on selection  I am displaying divs (none,1,2,3 etc). So the above approach (using ng-hide declaratively on each div)  is the best practice in angular ?

Thanks in Advance
