Creator Plugins UI Library

@lottiefiles/creator-plugins-ui — 25 accessible components built on Base UI + Tailwind CSS + CVA. Used in plugin UI code (src/) only, not the plugin sandbox.

Quick Setup

Full guide: references/setup-guide.md

npm install @lottiefiles/creator-plugins-ui

// src/main.tsx — import before local styles
import "@lottiefiles/creator-plugins-ui/styles.css";

Components and theme color utility classes (bg-primary, text-foreground, border-border, etc.) work with just styles.css — no Tailwind configuration needed.

If you need additional custom Tailwind classes beyond what the library provides, set up Tailwind v4:

npm install --save-dev tailwindcss @tailwindcss/vite

Add tailwindcss() to vite.config.ts plugins, create src/styles.css with @import "tailwindcss", and use @theme {} for custom colors. Do not create tailwind.config.js or postcss.config.js (v3 patterns). See references/setup-guide.md for full instructions.

Import Pattern

import { Button, Input, Select, Slider, cn } from "@lottiefiles/creator-plugins-ui";

Available Components

For props, variants, and API details, read the TypeScript types from the installed package — they include JSDoc comments, explicit union types, and default values:

node_modules/@lottiefiles/creator-plugins-ui/dist/components/*/

Components: Button, Input, Label, Select, Slider, NumberInput, DualNumberInput, Checkbox, Toggle, RadioGroup, Tabs, Dialog, Dropdown, Tooltip, SegmentedControl, SearchBar, Toast, Spinner, Separator, Card, Grid, EmptyState, Badge, AIPromptInput, ThemeProvider

Compound components (use sub-component composition): Dialog, Select, Dropdown, Tabs, Card, Tooltip, Toast, RadioGroup

Compound Component Pattern

Compound components (Dialog, Select, Dropdown, Tabs) use sub-component composition. Use render prop for polymorphic rendering (not asChild — this library uses Base UI, not Radix):

<DialogRoot>
  <DialogTrigger render={<Button variant="outline" />}>Delete</DialogTrigger>
  <DialogContent>
    <DialogHeader>
      <DialogTitle>Delete Layer?</DialogTitle>
      <DialogDescription>This cannot be undone.</DialogDescription>
    </DialogHeader>
    <DialogFooter>
      <DialogClose render={<Button variant="outline" />}>Cancel</DialogClose>
      <Button variant="destructive" onClick={handleDelete}>Delete</Button>
    </DialogFooter>
  </DialogContent>
</DialogRoot>

Theming

Full guide: references/theming-guide.md

Dark mode: add class="dark" to <html> — document.documentElement.classList.add("dark").

Runtime overrides with ThemeProvider:

<ThemeProvider tokens={{ "--primary": "hsl(260 80% 55%)" }} themeName="custom">
  <App />
</ThemeProvider>

Key CSS variables: --background, --foreground, --primary, --secondary, --destructive, --muted-foreground, --border, --ring.

cn() Utility

Use cn() from the library (not a local clsx) — it includes custom Tailwind merge config for theme colors and font sizes:

import { cn } from "@lottiefiles/creator-plugins-ui";
<div className={cn("p-4 text-foreground", isActive && "bg-primary")} />

Common Pitfalls

1. Missing styles.css import — Components render unstyled. Import @lottiefiles/creator-plugins-ui/styles.css once in entry file.
2. Using Tailwind v3 config with v4 — Do not create tailwind.config.js or postcss.config.js. Tailwind v4 uses @import "tailwindcss" + @theme {} in CSS and @tailwindcss/vite for Vite integration.
3. Using asChild instead of render — Base UI uses render={<a href="/" />}, not Radix's asChild + Slot.
4. Select empty string values — "" is reserved for "no selection". Use "none" or similar.
5. NumberInput is controlled only — Requires value + onChange. No uncontrolled mode.
6. Slider value is always an array — Pass [50] not 50. Callback returns array too.
7. Toast requires provider — useToast() throws outside <ToastProvider>. Wrap app root.
8. Dark mode class placement — dark class goes on <html> or parent, not on the component.
9. Wrong cn import — Use cn from @lottiefiles/creator-plugins-ui, not a local clsx.

Migration from Custom Components

Full before/after examples: references/setup-guide.md

1. Replace @stitches/react styled components with library components + Tailwind classes
2. Replace @radix-ui/* imports with library components
3. Replace asChild with render prop
4. Replace data-[state=checked] → data-[checked], data-[state=open] → data-[open], etc.
5. Replace inline colors with CSS variable classes (text-foreground, bg-primary)
6. Replace custom cn()/clsx() with library's cn()
