Search, the basemap gallery and bookmarks are Esri's own widgets placed with no code; the parcel panel, the four analyses and a true-ground-scale readout are custom widgets written once by a developer and placed by an analyst; the coded build traces a valve's isolation and inspects a feature's connections where the configured build uses popups instead. The series closes on a decision guide — who will maintain it, what it must do, and where it will live. https://www.youtube.com/embed/hJz3cD9geu8 252
