The mega menu component is a full-width dropdown that can be triggered by clicking on the menu item and it shows a list of links that you can use to navigate through the pages on a website.

<Htwo label="Setup" />

```html
<script>
  import { MegaMenu } from 'flowbite-svelte'
</script>
```

<Htwo label="Default mega menu" />

Use this example to show a list of links aligned on three columns inside the mega menu dropdown.

```svelte example class="h-80 md:h-64"
<script>
  import { Navbar, NavBrand, NavHamburger, NavUl, NavLi, Chevron, MegaMenu } from 'flowbite-svelte'
  let menu = [
    {name: 'About us', href: '/about'},
    {name: 'Blog', href: '/blog'},
    {name: 'Contact us', href: '/contact'},
    {name: 'Library', href: '/library'},
    {name: 'Newsletter', href: '/news'},
    {name: 'Support Center', href: '/support'},
    {name: 'Resources', href: '/resource'},
    {name: 'Playground', href: '/play'},
    {name: 'Terms', href: '/terms'},
    {name: 'Pro Version', href: '/pro'},
    {name: 'License', href: '/license'},
  ];
</script>

<Navbar let:hidden let:toggle>

  <NavUl {hidden}>
    <NavLi href="/">Home</NavLi>
    <NavLi><Chevron aligned>Mega menu</Chevron></NavLi>
    <MegaMenu items={menu} let:item>
      <a href={item.href} class="hover:text-blue-600 dark:hover:text-blue-500">{item.name}</a>
    </MegaMenu>
    <NavLi href="/services">Services</NavLi>
