Embedding Video
The process is the same as for a desktop application. You will need to define an attribute of the Document type in some object and then add an HTML cell to your form with the following contents:
<div style=”width:400px;height:400px”><<MyObject.DocumentAttribute>></div>
The div element is just to give width and height to the video. The actual video is embedded by a reference to the document attribute MyObject.DocumentAttribute
