How can I use Vue Teleport for advanced scenarios?

Vue Teleport allows you to render components outside of their parent hierarchy. For advanced usage, you can manage modals, tooltips, or dropdowns that need to escape overflow or z-index issues.

Can you give me an example of using Teleport for a modal?

Sure! You can create a modal component and use Teleport to render it in a specific DOM node, like this:

<template>
  <teleport to="#modal">
    <div class="modal">
      <slot></slot>
    </div>
  </teleport>
</template>

What are some common pitfalls when using Teleport?

Common pitfalls include not managing the modal's visibility properly, which can lead to accessibility issues, and forgetting to handle the focus trap when the modal is open.

How does Teleport affect performance?

Teleport itself is lightweight, but rendering large components outside the normal flow can impact performance if not managed correctly. Always test for performance in your specific use case.
