Shadcn Dialog 1 Block

For AI Agents

Hand your agent this brief or the ReUI MCP, not a screenshot. Installs with a ReUI Pro or Ultimate license.

Best for: A start and end time on a 30 minute grid, where 6 presets keep the start, move the end and wrap past midnight

When to use

New record forms over the current page: a project, a quick task or entry, or a finance account
Access flows: email invites with a role, an app picker and the consent step before a sync
Pickers and account tasks: a time span, a starter template, settings, a checklist, cancellation or help

When not to use

A full event form where the span sits beside a date, members and an image: use the Create Schedule block
A single hour and minute field in a form, with no span or presets: use the Time Picker component
A plain modal shell you fill with your own title, body and buttons: use the Dialog component
A data entry layout that sits in the page itself rather than over it: use the Form blocks
A one question confirm, such as deleting a record, with nothing to fill in: use the Alert Dialog component

Agent notes

Apply only calls setOpen; read startTime and endTime there and hand the span to your scheduler
Replace the 48 half hour TIME_OPTIONS and 6 DURATION_PRESETS in data.ts; a preset off the slot grid leaves the end at the start
Times are HH:MM strings with no date, and getDurationMinutes counts an end at or before the start as the next day
Each root renders its own launch Button and starts open as true in useState; swap in your trigger and start it closed
Primary actions only close through setOpen, fire a sonner toast or have no handler; wire your submit and API call there
Each page.tsx centers the root in a min-h-svh main with an sr-only h1; mount only the root component inside your page

Can I restyle the Duration Picker block?

How should I use Shadcn dialog blocks in a real project?

Treat them as structured starting points. Keep the layout, hierarchy, and interaction ideas that work, then replace placeholder content, data wiring, and business logic with your own product requirements.
