# useProxySlot

useProxySlot allows you to observe the nodes assigned to a slot and reassign them to another slot dynamically, example:

**Input**: Suppose we have a component that observe the slot\[name="slide"] node

```html
<my-component>
    <img slot="slide" src="slide-1"/>
    <img slot="slide" src="slide-1"/>
    <img slot="slide" src="slide-1"/>
</my-component>
```

**output**: thanks to useProxySlot you will be able to modify the assignment of the list nodes without losing the nodes in the process as normally happens with useSlot, example:

```html
<my-component>
    <img slot="slide-1" src="slide-1"/>
    <img slot="slide-2" src="slide-1"/>
    <img slot="slide-3" src="slide-1"/>
</my-component>
```

### Syntax and example

```jsx
import { useRef } from "atomico";
import { useProxySlot } from "@atomico/hooks/use-slot";

function component() {
  const ref = useRef();
  const children = useProxySlot(ref);

  return (
    <host shadowDom>
      <slot name="slide" ref={ref} />
      {children.map((child, index) => (
        <slot name={(child.slot = "slide-" + index)} />
      ))}
    </host>
  );
}
```

{% hint style="info" %}
All redirected hooks must exist under a slot

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://atomico.gitbook.io/doc/packages/atomico-hooks/use-slot/useproxyslot.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
