A Dreamweaver template (.dwt) file is just an HTML file with some additional markup, so there's no particular reason you can't work with a template in Edge Animate. The only practical roadblock is that Edge Animate isn't programmed to understand that files with the ".dwt" file name extension are HTML files. It is fairly easy to work around this.
Here's a summary of one possible method:
The only thing from here is to make sure all the necessary include files and assets are copied over to your Dreamweaver local site root folder along with the new template file.
Thanks for the work around. I created a main.html and I am working with it in Edge. Once finished I will covert it to a template in DW if that does not work I will try your process; Much appreciated Thank You!
