In DNN the Persona Bar is the admin control bar for managing sites. The Persona Bar is highly customizable from the top-level admin controls to the individual admin modules. The nice thing about developing modules for the Persona Bar is you do not need to use a specific development technique. The platform allows you to inject whatever HTML, JS, and CSS you choose, as long as you follow a few basic rules. Let's look into adding an Uno Platform app into DNN as a Persona Bar Component.
