Readme
Keep track of descendant components and their relative indices.
A descendant index solution for better accessibility support in compound components.
Note 🚨: This package is primarily intended for internal use by the Chakra UI library. You should not use it directly in your production projects.
yarn add @chakra-ui/descendant
# or
npm i @chakra-ui/descendant
Descendants observer is a utility hook for keeping track of descendant elements and their relative indices.
In short, this package allows each item in a list to know its relative index and the parent of the list can keep track of each child, without needing to render in a loop and pass each component an index.
This enables component composition:
<List>
<Item /> // I'm index 0
<Item /> // I'm index 1<div>
<div>
<Item /> // I'm arbitrarily nested, but still know that I'm index 2
</div>
</div>
</List>
