# Additional Description for Options
The Additional Description feature in YayExtra allows you to add extra information to each option in your product add-ons.
**Why use it?**
Sometimes, a simple option name isn’t enough to explain what customers are choosing. With Additional Description, you can provide more details to help them understand better and make confident decisions.
**How it works?**
When setting up an option type (like checkbox, radio button, or select), you’ll see a field called Additional Description. Simply enter the extra information you want to show.
This description will appear alongside the option on the product page.
**Example**
Option: Gift Wrapping
Additional Description: Includes premium paper and a handwritten note

## 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://docs.yaycommerce.com/yayextra/how-it-works/additional-description-for-options.md?ask=&goal=
```
`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.
