Expand attribution information on Webmaps

Idea created by WellingtonCityCouncil on Apr 23, 2018

    We have many clients who supply data that would like to be attributed in our webmaps (https://developers.arcgis.com/terms/attribution/). Unfortunately, unless the data is in a basemap format, the attribution will not appear automatically on the webmap. Can the "esri-attribution esri-widget" be modified to acquire attribution data from feature layers as well as basemaps?
