Yes, you can and should use symbols within symbols. It can be a very powerful way to reuse elements in multiple locations but only defining it once!
Now this is going to be a lame question but I seem to be having a brain freeze-
I have my "page" (.html) with everything on it.
At the top of the page, I'm creating a banner(banner1). This "banner" is a symbol within the project page.
I want to break it into three separate symbols(banner1, banner2 & banner3), all to run consecutively on the .html page inside the Edge project..
My thinking was that "If I could break this into three parts, it would make my life that much easier - plus I can then use 2 of those parts on other pages yet to be created!"
So, I first tried to "copy" the second part (already completed as part of banner1) onto a new page but it didn't copy very well at all, leaving parts in the timeline all over the place.
What is the best way to crete a new symbol out of a piece of symbol "banner1" already written?
Then I thought I'd just start on the third part for now but don't know how(or remember) to start. Within the symbol "banner1", I went to the end of my timeline and drew a black rectangle that encompassed the symbol's "stage" which is black (I can't create a symbol from the stage), thus creating a symbol. Is this a good way to do it, or should I just add my first item at the end of the symbol "banner1's" timeline and create a symbol out of that? I don't know why I thought about creating the black background - my mind works that way at times :-)
I hope this makes sense and thanks for the help!
