Dashboard UI Patterns

Reference templates for building and modifying dashboard pages. Use this when creating new pages, loading states, error states, or sheet/sidebar components.

Page Height Constants

Import from @/lib/utils/constants. These ensure consistent full-viewport layouts across all dashboard pages.

import { PAGE_HEIGHT_CLASS } from "@/lib/utils/constants";

How to decide: If the page uses <PageFooter>, use WITH_FOOTER. Otherwise use WITHOUT_FOOTER.

Loading State Templates

Page WITH footer

// loading.tsx
<PageContent withFooter>
  <Loader
    className={PAGE_HEIGHT_CLASS.WITH_FOOTER}
    message={t("loading")}
  />
</PageContent>
<PageFooter>&nbsp;</PageFooter>

Page WITHOUT footer

// loading.tsx
<PageContent>
  <Loader
    className={PAGE_HEIGHT_CLASS.WITHOUT_FOOTER}
    message={t("loading")}
  />
</PageContent>

Error State Templates

Use InfoPanel centered with appropriate height class.

// error.tsx pattern
<PageContent
  className={cn(
    PAGE_HEIGHT_CLASS.WITHOUT_FOOTER,
    "flex items-center justify-center"
  )}
>
  <InfoPanel
    title={t("error.loadError")}
    description={error.message || t("error.unexpectedError")}
    icon={<WarningIcon size={40} />}
    iconColor="text-destructive"
  >
    <Button onClick={reset}>{t("error.tryAgain")}</Button>
  </InfoPanel>
</PageContent>

InfoPanel children layout: Children render inline with centered buttons. Multiple buttons appear side-by-side.

<InfoPanel title="..." description="...">
  <Button>Action 1</Button>
  <Button>Action 2</Button>
</InfoPanel>

Sheet / Sidebar Scroll Pattern

For sheets with scrollable content, use this flex layout recipe:

<SheetContent
  side="right"
  className="flex w-full max-h-[100dvh] flex-col gap-0 overflow-hidden sm:max-w-md"
>
  <SheetHeader className="shrink-0 border-b border-border">
    {/* Header content */}
  </SheetHeader>

  <div className="flex min-h-0 flex-1 flex-col overflow-hidden">
    <div className="shrink-0 px-6 py-4 border-b">
      {/* Fixed content (filters, tabs, etc.) */}
    </div>
    <div ref={scrollRef} className="flex-1 overflow-y-auto px-6 py-4">
      {/* Scrollable content */}
    </div>
  </div>
</SheetContent>

Key principles:

• max-h-[100dvh] and overflow-hidden on SheetContent
• shrink-0 on fixed elements (headers, footers)
• min-h-0 flex-1 overflow-hidden on the scrollable wrapper
• flex-1 overflow-y-auto on the actual scrollable area

Workflow: Finding Real Examples

When applying these patterns, explore the codebase for existing implementations:

1. Search for existing loading states: Glob("src/app/**/loading.tsx")
2. Search for existing error states: Glob("src/app/**/error.tsx")
3. Search for sheet patterns: Grep("SheetContent", glob="src/components/**/*.tsx")
4. Search for PAGE_HEIGHT_CLASS usage: Grep("PAGE_HEIGHT_CLASS", glob="src/**/*.tsx")

Use these real implementations as reference alongside the templates above.

Icons

Always use Phosphor Icons. lucide-react is banned via linting.
