Source: https://www.morphicons.com/

Use the MorphIcon component to animate between two icons by passing the desired icon as a prop. The library handles the transition automatically without requiring explicit from/to pairs.

```tsx
import { MorphIcon } from "morphicons/react";
import { Menu, X } from "lucide"; // data, not components

<button onClick={() => setOpen(o => !o)} aria-expanded={open}>
  <MorphIcon icon={open ? X : Menu} />
</button>
```

const open = ref(false);

<template>
  <button @click="open = !open" :aria-expanded="open">
    <MorphIcon :icon="open ? X : Menu" />
  </button>
</template>
