Hi, wizard implementation can be found under /libs/dam/gui/content/projects/addtask and drop-down can be found here /libs/cq/gui/components/projects/admin/userpicker. Unfortunately both those areas are marked as granite:InternalArea. Based on AEM documentation Internal (granite:InternalArea) - Defines a node as internal. Nodes classified as internal cannot be overlaid, inherited, or used directly. These nodes are meant only for internal functionality of AEM I have been assigned the same use case...

I found userlist.jsp which is in the userpicker folder but cannot locate userlist.html, can you please help?
