What are some advanced examples of using portals in Vue 3?

In Vue 3, portals allow you to render content outside of the parent component's DOM hierarchy. An advanced example is creating a modal component that can be triggered from anywhere in your app.

Can you show me how to implement a modal using portals?

Sure! First, create a modal component that uses the Teleport feature. Then, you can trigger it from any component by managing its visibility state.

What about using portals for tooltips or dropdowns?

Absolutely! You can use portals for tooltips by rendering them in a fixed position relative to the target element, ensuring they don't interfere with layout.

Are there any performance considerations when using portals?

Yes, while portals are efficient, rendering too many at once can impact performance. It's best to manage their visibility and lifecycle carefully.
