Custom Element Not Appearing on Form

Hey Everyone,

I am making a custom dropdown following this example (https://niteco.com/blogs/how-to-extend-episerver-form/#disqus_thread)

The admin section seems to be working, but I cannot get the item (the View) to appear on the form.  I am not getting any errors, but I also cannot step through the Razor code. I cannot figure out what I am missing.

This is where the cshtml is stored.

formElementViewsFolder="~/Views/Shared/ElementBlocks"

Does anyone have ideas on how to troubleshoot this and get it working?
