# Sections
{% hint style="info" %}
This feature is available on the Ultimate site plan.
{% endhint %}
Example of a GitBook site with sections
Sections let you centralize your documentation in one site. Use them to organize separate products. You can also serve different audiences with tailored content.
Group sections to create a dropdown in your navigation bar. Groups add hierarchy to your site.
### Sections or variants?
Each section holds its own content. Use sections for distinct documentation areas. These can represent products, audiences, or topics.
For variations of the same content, use [content variants](/docs/manage-your-site/site-structure/variants.md). Variations include localizations and historical product versions.
### Add a section
To add a section:
1. In the site sidebar, open **Site structure**.
2. Below the table, click **New section**.
3. Select the content to add.
The section appears in the table. It also appears as a tab on your published site.
Add structure to your docs with sections.
### Create a section group
Section groups create a navigation dropdown under one heading. Grouped sections can have an optional description. The description appears below the section title.
To create a group:
1. Next to **New section**, click the arrow.
2. Select **New section group**.
3. Enter a group name.
4. Click **Add section**.
5. Add existing sections or select new content.
If your site supports multiple languages, translate group titles, section titles, and descriptions. See [Multilingual sections](/docs/manage-your-site/site-structure/multilingual-sections.md).
### Edit a section
To edit a section:
1. In the section’s table row, click **Edit**.
2. Change the name, icon, or slug.
3. Click **Save**.
To delete a section, click **Delete** in the lower-left corner.
{% hint style="info" %}
Changing a section’s slug changes its canonical URL. GitBook creates a redirect from the old URL. You can also [create redirects manually](/docs/publish/site-redirects.md).
{% endhint %}
### Reorder sections
Sections appear in the same order as the **Site structure** table. To reorder a section, drag its drag handle up or down. The section’s content moves with it. The new order appears on your site immediately.
To use a keyboard:
1. Press **Space** to select a section.
2. Press an arrow key to move the section.
3. Press **Space** to confirm.
### Set the home section
The home section appears when visitors open your site. It loads at your site’s root URL. Other sections add a slug to the root URL.
To set the home section:
1. In the section’s table row, open the **Actions** menu.
2. Click **Set as home**.
### Set the home variant
If a section has multiple variants, choose which variant visitors open first.
To set the home variant:
1. Open **Site settings**.
2. Click **Structure**.
3. Click the section to update.
4. Find the variant visitors open first.
5. Click **Set as home**.
### Remove a section
To remove a section:
1. In the site sidebar, open **Site structure**.
2. Open the section’s **Actions** menu.
3. Click **Remove**.
{% hint style="success" %}
Removing a section unpublishes it and its variants. It doesn’t delete the content. You can still find it in [All content](/docs/create-content/content-structure/all-content.md).
{% endhint %}

## 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://gitbook.com/docs/manage-your-site/site-structure/site-sections.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.
