I used the DMXzone extension manager to install MySQLi Server Behaviors. Now in Dreamweaver where do I find it?
Update: I finally got it. The first installation attempt was probably messed up. So I reinstalled the extensions and rebooted. My screen doesn't quite match what's on the WebAssist video but I found the behaviors. One issue that's very annoying, I can only drag database fields to the design window, not the code window. A crossed-out cursor appears when dragging to the code window. I'm running Dreamweaver CC 2017. In most cases I can't position the field exactly where I want it in the design view, so I have to cut and paste in the code view. It works but adds a lot of extra time. Hopefully all of this is temporary and someone, WebAssist or Adobe, will come up with a more elegant solution.
And, by the way, thanks to everyone for the fast replies. I does mean a lot and is apprecieated!
