How do I use portals in Vue 3?

In Vue 3, you can use the Teleport component to create portals. It allows you to render a component outside of its parent hierarchy.

Can you show me a simple example of using Teleport?

Sure! Here's a basic example:

<template>
  <div>
    <h1>Main Component</h1>
    <Teleport to="#portal">
      <div>This will be rendered in the portal!</div>
    </Teleport>
  </div>
</template>

What is the purpose of using Teleport?

Teleport is useful for rendering components in different parts of the DOM, like modals or tooltips, without affecting the component hierarchy.

Are there any limitations to using Teleport?

Yes, one limitation is that the target element must exist in the DOM when the Teleport is rendered. Also, it doesn't manage state across different locations.
