How found it:
I was going to try WebRTC tech because of it i am trying to do things i did in demo step by step i completed all the steps and came across this simple error.
Error:
If user Right Clicks Component and clicks Online Help Its says element should be div
This is a mistake in the online doc. We will correct this. The PDF manual is correct. TWebListBox maps on a HTML SELECT element, hence, a SELECT element needs to be used in the template.
