Re: [Dynapi-Help] Dynapi3 getContentWidth and Template

[<ml...@id...>]

Okay, what is the correct way to do the following then:

	  Have containers sized so that the entirety of their contents are
	  visible.


I have a template that I change the content of. I want the object it
is in display the entire template contents.

And so on up the tree of containers till I get to the dynapi.document.

Basically, I have templates and other objects that change as the user
interacts with the page. I want the entire content to be visible to
the user.
