Explain Teleport and its typical use cases.

Updated May 4, 2026

Short answer

Teleport allows you to 'move' a component's template content to a different part of the DOM outside its nesting.

Deep explanation

Even though a component is logically nested in the hierarchy (inheriting props/state), its DOM output might need to live elsewhere (e.g., directly under <body>) to avoid CSS issues like z-index conflicts or overflow: hidden. Teleport maintains the component's internal state and reactivity while placing the DOM nodes elsewhere.
