Why Named Slots
Components often need multiple insertion points: a header, a body, and a footer for example.
Defining Named Slots
Add a name attribute to the slot element in the child.
<!-- Layout.svelte -->
<header><slot name="header" /></header>
<main><slot /></main>
<footer><slot name="footer" /></footer>Filling Named Slots
From the parent, mark elements with a slot="name" attribute.
<Layout>
<h1 slot="header">Title</h1>
<p>Body</p>
<p slot="footer">Copyright</p>
</Layout>Mixing Default and Named
Content without a slot attribute fills the default slot. Named content goes to its named slot.
Order Independence
The order in the parent does not matter. Each slot is matched by name.
Multiple Elements per Slot
Wrap multiple elements in a single host with the slot attribute to send them all to the same slot.
Conditional Headers
Use {#if} in the parent to optionally fill named slots.
Common Layouts
This pattern is great for layouts with header/sidebar/main/footer.
Form Components
Form components might define slots for prefix, suffix, helper text, etc.
Self-Documentation
Slot names describe the component's API. Pick descriptive ones like title or actions.
TypeScript Helpers
You can type slots with a special $$Slots generic in TypeScript Svelte files.
