A Material Design checkbox (pp_checkbox/1).

Accepts either a Phoenix Phoenix.HTML.FormField via field= (idiomatic to_form/2 usage, same as the default core_components.ex input) or plain name/checked attrs.

When paperize is false this renders a bare native <input type="checkbox"> (no hidden-input trick, no custom box) so it never fights a caller's own CSS — class targets that bare input directly in this case (not the wrapping <label>, which keeps its own unconditional layout classes regardless of paperize; see PhoenixPaper.Helpers.toggle_label_classes/1), so e.g. class="size-5" sizes the checkbox itself as expected.

ripple={true} adds the Material ripple effect on click/tap, wired to the small box rather than the whole label — off by default (unlike Button/Fab/ToggleButton), since a checkbox's own instant fill/border-color change already reads as clear feedback on a target this small — see PhoenixPaper.Ripple.
