# Structure

{% embed url="<https://www.youtube.com/watch?v=I-y-b-1Sgxg>" %}

Learn how the Flexi Theme Library structure works in Shopify. Every Flexi section follows a four-tiered structure:

{% stepper %}
{% step %}

#### Sections

The top-level container that defines a reusable component, like a hero banner or product slider. Sections can be dropped into any Shopify theme.
{% endstep %}

{% step %}

#### Layouts

Each section contains one or more layout options—these control the structure, such as a single-column, grid, or split layout.
{% endstep %}

{% step %}

#### Groups (Optional)

Groups organize related content or functionality within a layout. They let you bundle settings or blocks together (e.g., “Card”, “Image Background”) for clearer content management.
{% endstep %}

{% step %}

#### Blocks

The most granular unit in Flexi. Blocks are individual content elements—like headings, images, buttons—that can be mixed and matched inside groups.
{% endstep %}
{% endstepper %}

## 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://flexi-library.gitbook.io/flexi-sections/docs/global-styles.md?ask=<question>&goal=<endgoal>
```

`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.
