> Deprecated: > Product subscription app extensions won't be supported as of December 3, 2025. You should migrate existing product subscription app extensions to [purchase options extensions](/docs/apps/build/purchase-options/purchase-options-extensions). CardSections are used to group similar concepts within a Card. CardSections add dividers, which visually separate regions within cards.

## Props optional = ? | Name | Type | Description | | --- | --- | --- | | title? | string | | ## Guidelines | ✅ Do | 🛑 Don't | | ----------------------------------------------- | ------------------------------- | | Use CardSection to split up content within Card | Use CardSection outside of Card |
