I have been asked on multiple occasions for help with registering a custom widget in ArcGIS Enterprise. My answer has always been, "I don't know. My Enterprise is still on 10.9.1." Well, that is changing. We are upgrading to Enterprise 11.3 and now that our testing portal has crossed the threshold into that magic 11.X world that allows for hosting custom widgets, I have hosted some widgets. So, I'm going to walk you through the process and what I learned along the way.
The first thing I did was pull up the official documentation, which was rather good in this case. Ordinarily, I'd drop a link here, but the document is imbedded within Enterprise itself on an internal server. I found it by opening Experience Builder, scrolling down the Insert Widget Pane and hitting the question mark next to Custom. Also, note that the box with the lines on it will take you to the Item Page on your Portal, so if you want to make your own documentation for your custom widget, that would be the way to find it. Nice touch,
