# Multiple EPREL Numbers & Titles
For complex products like kitchens or appliance bundles, the app supports displaying **multiple energy class badges** on the product page — each with its own **custom title**.
To enable this feature, enter all EPREL numbers into the **EPREL Registration Number** metafield at the **product level**, using the following format:
```
1576181 [Dishwasher Siemens SN65YX00CE], 160567 [Oven Bosch HVA331BS0], 1776798 [Refrigerator Liebherr IRBPbsci 5170 BioFresh]
```
* The **number** is the EPREL registration number for the product.
* The **title** in **square brackets** is a custom label that will be displayed alongside the corresponding energy badge.
* Use a **comma** to separate each EPREL number and title pair.

**Important notes:**
1. Works only with the product-level **EPREL Registration Number** metafield. Shopify variants are not supported.
2. Multiple energy badges are only displayed on the Product page.

## 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://staylime.com/docs/energy-label/advanced-setup/multiple-eprel-numbers-and-titles.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.
