Select
Choose one value from a known set with a compact trigger.
Overview
Choose one value from a known set with a compact trigger. This entry is written as a registry-ready component spec: useful to humans, copyable by AI tools, and easy to map to a future shadcn registry item.
Anatomy
- Trigger
- Value
- Content
- Item
- Indicator
Variants
- default
- muted
- error
- disabled
States
- default
- hover
- focus-visible
- disabled
- error
- filled
Component spec
Styling tokens
Accessibility notes
- Use semantic HTML or the matching Radix primitive before custom roles.
- Keep focus-visible states obvious without adding decorative glow.
- Ensure icon-only controls have an accessible label.
- Do not rely on color alone for state or validation.
shadcn implementation
Use Radix Select through the matching shadcn component when possible.
Use shadcn tokens for background, border, ring, muted text, radius, and state variants. Keep component-specific classes local and copyable.
HeroUI mapping
Select can map to a HeroUI component only as an optional adapter. Keep UnBoring copy and token language framework-neutral.
Create a Select component for an AI-generated interface using shadcn-style composition. Use shadcn/ui select as the implementation base. The component should support default, muted, error, disabled variants and default, hover, focus-visible, disabled, error, filled states. Include clear anatomy for Trigger, Value, Content, Item, Indicator. Keep the visual language black, white, and gray with subtle borders, practical spacing, accessible focus states, and no decorative noise.
Do not invent a custom component API when shadcn/ui select already covers the base behavior. Avoid random gradients, oversized radii, unclear disabled states, missing labels, icon-only controls without accessible names, and variants that change layout unexpectedly.
Base: shadcn/ui select Primitive: Radix Select Tailwind: Use shadcn tokens for background, border, ring, muted text, radius, and state variants. Keep component-specific classes local and copyable. Dependency: Use Radix Select through the matching shadcn component when possible.

Usage notes
Short guidance for humans and AI tools before copying the component.
Select helps teams choose one value from a known set with a compact trigger. It should feel like a reusable product primitive, not a one-off decoration.
Start from shadcn/ui select. Use Radix Select through the matching shadcn component when possible. Keep variants token-driven and keep states predictable.
Do not invent a custom component API when shadcn/ui select already covers the base behavior. Avoid random gradients, oversized radii, unclear disabled states, missing labels, icon-only controls without accessible names, and variants that change layout unexpectedly.
