Shadcn Dialog Examples: Modal Windows That Respect Focus
A dialog is a modal window that interrupts the user with important content and expects a response before the page underneath becomes interactive again. The shadcn dialog component delivers this react modal dialog with focus trapping, escape-to-close, overlay dismissal, and scroll locking already handled, styled entirely with Tailwind CSS so it matches the rest of your interface.
On this page you will find copy-paste dialog examples including a basic confirmation layout and a share link dialog with an input and copy action. Both are TypeScript, animate in and out with data-state attributes, and slot directly into a Next.js App Router project.
Key features
- Focus management: Focus moves into the dialog on open and returns to the trigger on close, which keyboard users depend on.
- Escape and overlay dismissal: Pressing Escape or clicking the backdrop closes the dialog, with both behaviors overridable for critical flows.
- Accessible labeling: DialogTitle and DialogDescription wire aria-labelledby and aria-describedby automatically.
- Controlled or uncontrolled: Use the open and onOpenChange props for programmatic control, or let the trigger manage state for simple cases.
- Scroll lock and portal: Content renders in a portal above the page and background scrolling is locked while open.
Best practices
- Always include a title: Screen readers announce the DialogTitle on open, so never ship a dialog without one.
- Keep it to one task: A dialog should complete a single decision or short form. Multi-step journeys belong on a page.
- Offer an explicit close: Provide a visible cancel or close button rather than relying only on Escape and overlay clicks.
- Avoid nesting modals: A dialog opening another dialog disorients users. Restructure the flow or use inline expansion instead.
- Reserve interruption for importance: If the content does not need an immediate response, a sheet or inline panel is less disruptive.
Common use cases
Short forms are the sweet spot: creating a project, renaming a file, or inviting a teammate all fit a dialog with a field or two and a submit button. The share link example on this page shows the copy-to-clipboard pattern used across SaaS products.
Destructive confirmations deserve special mention. When deleting data, prefer the alert dialog, which blocks outside dismissal so the user must choose explicitly. For editing sessions with more content, a side sheet or a drawer on mobile keeps context visible.
Composing dialogs in real apps
Dialogs commonly wrap forms whose triggers live inside a dropdown menu row action, a pattern that requires controlling open state above both components. Full CRUD flows built this way, dialog forms launched from table rows, appear throughout our admin blocks if you want complete wired pages.
Radix UI and Base UI support
The default implementation composes the Radix UI Dialog primitive, which supplies the portal, focus trap, and aria wiring. An equivalent build on the Base UI dialog exposes the same part names, so the Tailwind CSS layer transfers between ecosystems. The anatomy for both is covered in the shadcn/ui dialog docs, and these dialog examples keep to that anatomy so either primitive works.
