Rating

Star rating for both input and display, with half-star support. Use it to collect a score — rate this product, leave a review, a satisfaction or feedback rating, thumbs/stars on an order or support ticket — or, in read-only mode, to show an average score next to reviews, listings, or search results (an average like 3.7 fills 70% of a star). shadcn/ui ships no rating component. Works controlled or uncontrolled via a number value with onValueChange, forwards a ref, and posts through a hidden input in native forms via `name`. Set allowHalf to pick half stars — click the left half of a star, or step by 0.5 with the keyboard. Accessible as a slider: it's focusable with a focus-visible ring, arrow keys raise and lower the score, Home clears to 0 and End maxes out, and it exposes aria-valuenow plus a spoken aria-valuetext ("3.5 out of 5 stars"); read-only mode renders as a labelled image instead. The empty and filled stars are decorative and aria-hidden. Configure the number of stars with max and pixel size with size. Theme-aware via shadcn tokens (filled stars use the primary color, so it follows your theme in light and dark mode); only depends on lucide-react for the star icon.
