Enhance named examples display with select component

[coderabbitai]

Description

Currently, named examples in parameters are displayed inline with labels, which can become cluttered when multiple examples are present.

Suggestion

Consider implementing a select/dropdown component to display named examples, allowing users to choose which example to view. This would provide a cleaner UI and better user experience, especially when dealing with multiple named examples.

Context

This enhancement follows the implementation of basic named examples support in PR #299. The current implementation shows all examples inline, but a select component would be more space-efficient and user-friendly.
