import { useState } from "react";

function ContactForm() {
  const [email, setEmail] = useState("");

  return (
    <Card className="w-96">
      <CardHeader>
        <CardTitle>Contact Us</CardTitle>
      </CardHeader>
      <CardContent className="space-y-4">
        <div>
          <Label htmlFor="email">Email</Label>
          <Input
            id="email"
            type="email"
            placeholder="Enter your email"
            value={email}
            onChange={(e) => setEmail(e.target.value)}
          />
        </div>
        <Button className="w-full">Submit</Button>
      </CardContent>
    </Card>
  );
}

Using Navigation Components

import { Tabs, TabsContent, TabsList, TabsTrigger } from "@codefast/ui";

function TabExample() {
  return (
    <Tabs defaultValue="account" className="w-96">
      <TabsList className="grid w-full grid-cols-2">
        <TabsTrigger value="account">Account</TabsTrigger>
        <TabsTrigger value="password">Password</TabsTrigger>
      </TabsList>
      <TabsContent value="account" className="mt-4">
        <p>Make changes to your account here.</p>
      </TabsContent>
      <TabsContent value="password" className="mt-4">
        <p>Change your password here.</p>
      </TabsContent>
    </Tabs>
  );
}

Using Overlay Components

import {
  Dialog,
  DialogContent,
  DialogDescription,
  DialogHeader,
  DialogTitle,
  DialogTrigger,
  Button,
} from "@codefast/ui";

function DialogExample() {
  return (
    <Dialog>
      <DialogTrigger asChild>
        <Button variant="outline">Edit Profile</Button>
      </DialogTrigger>

      </DialogContent>
    </Dialog>
  );
}

Theming and Customization

The library uses Tailwind CSS for styling and supports theme customization:

import { ThemeProvider } from "next-themes";

function App() {
  return (
    <ThemeProvider attribute="class" defaultTheme="system" enableSystem>
      <div className="bg-background text-foreground min-h-screen">{/* Your app content */}</div>
    </ThemeProvider>
  );
}
