title: Dropdown list is not working in the Asp.net Blazor Component
body: <p>I am trying to learn the new feature in ASP.NET Blazor. I am using Visual Studio 2019. I am trying to create an Ideas Registration form. So the code for dropdownlist i had took from Bootstrap 4. It was not working as expected. Can you please tell me where i am working wrong?</p>
  
  <p>Just a little overwhelmed here, any advice would be much appreciated.</p>
  
  <p>Given Code: </p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;!-- Card Body --&gt;
  &lt;div class="card-body"&gt;
      &lt;!-- &lt;form   --&gt;
      &lt;form&gt;
          &lt;div class="form-group"&gt;
              &lt;label for="exampleFormControlInput1"&gt;Title&lt;/label&gt;
              &lt;input type="email" class="form-control" id="exampleFormControlInput1"&gt;
          &lt;/div&gt;
          &lt;div class="form-group"&gt;
              &lt;label for="exampleFormControlSelect1"&gt;Description&lt;/label&gt;
              &lt;textarea class="form-control" id="exampleFormControlTextarea1" rows="4"&gt;&lt;/textarea&gt;
          &lt;/div&gt;
          &lt;!-- Basic dropdown --&gt;
          &lt;div class="form-group"&gt;
          &lt;button class="btn btn-primary dropdown-toggle mr-4" type="button" data-toggle="dropdown"
                  aria-haspopup="true" aria-expanded="false"&gt;
              Basic dropdown
          &lt;/button&gt;
  
          &lt;div class="dropdown-menu"&gt;
              &lt;a class="dropdown-item" href="#"&gt;.Net&lt;/a&gt;
              &lt;a class="dropdown-item" href="#"&gt;Python&lt;/a&gt;
              &lt;a class="dropdown-item" href="#"&gt;Data Science&lt;/a&gt;
              &lt;div class="dropdown-divider"&gt;&lt;/div&gt;
          &lt;/div&gt;
          &lt;/div&gt;
          &lt;!-- Basic dropdown --&gt;
  
  </code></pre>
