We have webparts deployed using WebPartGallerySourceBase and WebPartGalleryItemBase instead of the traditional .webpart file. Should they show in the Snippet Gallery? (Design Manager -> Master Pages -> Conversion -> Snippets)
We have traditional ones which do show, however, the ones with custom source and item bases do not show. Wondering if it's a coding error, a miss from MS or something else. Is there something which can be done in order to get them to show? The custom ones work fine when editing a page.
Thanks!
