I want to use an iframe construction into my edge animate document.
Edge animate *.oam file's planned to be used into inDesign DPS-folio.
There is an iframe like <iframe src="local.html"></iframe> in that.
Have a look at this thread walkthrough for a different example
Follow the above link reference with noted differences for your example, outlined below:
2.g. - copy local.html into the /Assets folder
3.i. - create a require reference of type 'other' with the src set to local.html, like this
<require type="other" src="local.html" />
3.j. - Skip this one
