Hi Siva,

I tried something very quickly at my end. It is not a refined solution at this point, I leave that upto you to explore and extend it to suit your needs. My idea was just quickly check if this can be done or not.

I placed the below code in UserWorkForm fragment and launched a portal.

In this case, the below DIV will appear when the portal loads. After 5 seconds, the DIV disappears.

<div id="SampleMsg" style="display: block;">HELLO WORLD</div>

<script type="text/javascript">

    setTimeout(closeMsg, 5000);

 

   function closeMsg(){

     document.getElementById("SampleMsg").style.display = "none";

   }

</script>

Thanks,

Sunny
