# Implement product discovery and presentation

Get started by diving straight into one of our modules!

After completing this module, you should be able to:

<br />

- Explain how to use Categories in Composable Commerce to build a localized and scalable mega menu.
- Use the Composable Commerce SDK and APIs (REST and GraphQL) to query and transform Category data into a structured navigation tree.
- Assess and implement performance and caching strategies to ensure scalable and responsive navigation experiences.

After completing this module, you should be able to:

<br />

- Retrieve product data using various query methods, such as ID, key, and slug.
- Implement localization, price selection, and inventory filtering.
- Build dynamic product detail page features, such as variant switching and category breadcrumbs.
- Integrate high-quality media, customer reviews, and recommendations.
- Apply effective caching and error handling strategies.

After completing this module, you should be able to:

<br />

- Design and implement a functional product listing page using the Composable Commerce TypeScript SDK, incorporating features such as search, filtering, faceting, and pagination.
- Optimize product listing pages for usability and performance by applying best practices related to navigation, filtering, search refinement, and data presentation.

## Search

The docs website provides a search box that lets you find pages by keyword across the documentation.
