Widget Catalogue and Collection Extras¶
This page is a supporting reference for the Collections area. Use it when the main collections.md page is not enough and you need to focus on widget selection, list pages, or API-oriented outputs.
Use this page for¶
browsing available widgets for a collection
comparing suggested widget types
managing list or index-style outputs
understanding where API or machine-readable outputs attach to a collection
Widget selection¶
The widget picker helps you choose the right block for the current collection.

Expect the catalogue to group suggestions around the available data and to surface parameter forms when a widget needs more detail.
Collection extras beyond a single widget¶
Collections can also own outputs that are not just one visual block, for example:
index or list pages
collection-specific API outputs
reusable content structures that the Site stage can later place into pages
These features still belong to the same Collections stage even when the route
name in the app remains /groups.
