# Lightbox

In Kumu, you can embed content from external providers into a **lightbox**.

![Lightbox showing a YouTube video in Kumu](https://1181816445-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FkXSW1nEf49ISqGxYuRfS%2Fuploads%2Fgit-blob-ac20feb914a4c8d3cff079177da66a9ff228098c%2Flightbox-youtube.png?alt=media)

To show content in a lightbox, start by finding a link to the embeddable version of the external content. Once you have the link, just add add `?lightbox` to the end for the default lightbox, or add `?lightbox=full` for a nearly-fullscreen lightbox.

Add the completed link into one of the following places in your map:

* The Map Overview located in the [side panel](/overview/user-interfaces/map-editor.md#side-panel)
* The text for any [presentation](/guides/presentations.md) slide
* The Description field in any [profile](/guides/profiles.md)
* Any custom field with its [field type](/guides/fields.md#customize-a-field) set to Text or URL

{% hint style="info" %}
Tip: Add the lightbox to a custom field named `URL` with its type set to URL, and the lightbox will open when your element, connection, or loop is double-clicked.
{% endhint %}

{% hint style="info" %}
**Note:** If you're looking to put a Youtube video in a lightbox, make sure to use the full URL. More info [here](/guides/widgets.md#youtube).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.kumu.io/guides/lightbox.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
