title: How to add a RTF input box using adaptive card?
body: <p>I am creating a Teams bot. I want to enable user to provide input using adaptive card input box. How should I configure the adaptive card so it can enable the user to format the text they sent. I want to add RTF enabled editor.</p>
  
  <p>Current state:
  I have added Adaptive Card with below columnset</p>
  
  <pre class="lang-cs prettyprint-override"><code>new AdaptiveColumn()
  {
      Items=new List&lt;AdaptiveElement&gt;()
          {
              new AdaptiveTextInput()
                  {
                      Id="body",
                      Placeholder="Please type your message here",
                      IsMultiline=true,
                      Value=""
                  }
           },
           Width="100"
  }
  </code></pre>
  
  <p>Behavior: I get a input box to type in my message without any formatting option.</p>
  
  <p>Expected: I want to add a box which allows me to add a message and format it as per my need. Currently it supports few markups to format the text, but I'm looking for a rich text editor.</p>
