 <script src="https://cluster1.telifoun.com/webapi/en/mqttchat.js?appid=mqttchat-87226030&uf=0"></script>

In the body of your page, where you want to display MQTT chat, add #mqttchat div to show docked layouts.

 <div id="mqttchat"   
          data-layout="docked"   
          class="mqttchat-lite" 
          data-user-name="user"
          data-user-surname="126"
          data-user-link=""
          data-user-avatar=""          
          data-user-id="126"
          data-user-gender="0"          
     ></div>

In the body of your page, where you want to display MQTT chat, add #mqttchat div to show embedded layouts.

          data-user-name="user"
          data-user-surname="1"
          data-user-link=""

          data-user-gender="0"  
          data-width="950"
          data-height="650"        
     ></div>
