Column picker

How this page is built the gem renders it — this is all you write

Pass picker: true and a gear appears in the header row: the user ticks which columns are shown and (with the optional crud-columns Stimulus controller) drags to reorder them. It submits ?cols[]= to this same URL — like the sort links and filter row — so it opens and works without JavaScript. The picker groups every column by its source model (Pipedrive-style): own columns under this model, association and path columns under the model they reach — publisher.founded_on under Publisher, authors.email under Author. The selection is always intersected with the permitted set, so a forged ?cols= can only hide or reorder, never reveal one.
