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: Reply quoting above the composer, per comment resolve and delete, a reaction count toggle, and Mark all resolved in a header menu

When to use

  • Record detail opened over a list or table: a ticket, metric, cron job, audit event, deploy, SLO or data source
  • Create and edit forms in a side panel for a project, cron job, firewall rule, SLO or data connection
  • Utility panels for help guides, keyboard shortcuts, an AI assistant, comments, notifications or view settings

When not to use

  • A feed of system events with inline approve buttons, not a discussion: use the Notifications Feed block
  • A bare side panel with your own header, body and footer, nothing prebuilt: use the Sheet component
  • A persistent sidebar or navigation layout that stays around every page: use the App Shell blocks
  • An assistant conversation that fills the whole page rather than a side panel: use the AI Chat blocks

Agent notes

  • Replace INITIAL_COMMENTS, CURRENT_COMMENT_AUTHOR and COMMENT_THREAD_CONTEXT, the Stripe thread title and logo, with your thread data
  • Replies, reactions, resolves and deletes live only in comments, reactedCommentIds and resolvedCommentIds; persist them to your API
  • Both Copy link menu items and the composer emoji, mention and attach InputGroupButtons have no onClick
  • Each root renders a demo SheetTrigger button and opens on mount via defaultOpen or a useState seeded true; start it closed in your app
  • Each SheetContent className floats it inset with inset-y-4, right-4 and rounded-xl and sets its own width; resize it there, not in the primitive
  • Each page.tsx only centers the trigger in a min-h-svh main with an sr-only h1; render the root component alone inside your page

It is composed from Avatar, Badge, Button, Dropdown Menu, Field, Input Group, Item, Scroll Area, and more, so every part of it is a primitive you can restyle with your own design tokens.

What You Can Build With the Comment Thread Block

  • Install it with the ReUI registry command in the toolbar above, then swap the placeholder content, data wiring, and business logic for your own.
  • Compare it across all eight ReUI styles and both the Base UI and Radix bases in the customizer before committing to one direction.

Frequently Asked Questions

When should I use the Comment Thread block?

Use it for reply quoting above the composer, per comment resolve and delete, a reaction count toggle, and Mark all resolved in a header menu.

The Sheet category fits:

  • Record detail opened over a list or table: a ticket, metric, cron job, audit event, deploy, SLO or data source
  • Create and edit forms in a side panel for a project, cron job, firewall rule, SLO or data connection
  • Utility panels for help guides, keyboard shortcuts, an AI assistant, comments, notifications or view settings

For a feed of system events with inline approve buttons, not a discussion, use the Notifications Feed block. For a bare side panel with your own header, body and footer, nothing prebuilt, use the Sheet component. For a persistent sidebar or navigation layout that stays around every page, use the App Shell blocks. For an assistant conversation that fills the whole page rather than a side panel, use the AI Chat blocks.

What is the Comment Thread block built with?

Comment Thread uses Avatar, Badge, Button, Dropdown Menu, Field, Input Group, Item, Scroll Area, Sheet, Tooltip. Installing the block through the ReUI registry pulls those dependencies in for you.

Can I restyle the Comment Thread block?

Yes. It reads your design tokens, so switching style, radius, base color, font, or icon library in the customizer restyles it without touching the markup.

How should I use Shadcn sheet 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.
