# llimphi-widget-segmented Mutually exclusive option control. N horizontal options with ONE active. The iOS/macOS pattern for radio-style alternatives when there are few (2–5) and they fit on a line. If there are more, use `tabs` or a dropdown. Render-only: the app keeps `selected: usize` in the model and dispatches `Msg::SelectSegment(usize)` on click. --- Part of **llimphi** — see [llimphi](../../README.md).
