Hi Matt, I typically use “Bluefish” or “Atom” to develop and test custom jquery and .js widgets and then set them up in Percussion. I have found that you can do just about anything you want to do, if you think it through and are familiar with Percussion CM1. There is more than one way to accomplish something. For instance, you can place Javascript calls inside the Meta Data area, inside the .js path of the widget, and/or inside another separate HTML widget on the same page. When a page is published, it becomes a “mash”. Keeping that in mind, you can also view web source of a published widget, make alterations to it and re-paste it back into an empty HTML widget.
