To place a website into your Pod you need to use the HTML widget.
Drag this into your Pod, select the Code toggle, and then place in the following code;
<iframe src="https://www.sendtrumpet.com" height=600px width=100% title="description"></iframe>
(Replacing www.sendtrumpet.com with your website or whichever domain you choose)
You can then click the Preview toggle to see how this would look in your Pod.
Note - You can change and customise the HTML height and width as needed.
