# Configuration¶

A few configuration options for this theme

Note

This documentation and the examples below are written with MyST Markdown, a form of markdown that works with Sphinx. For more information about MyST markdown, and to use MyST markdown with your Sphinx website, see the MyST-parser documentation

## Source repository buttons¶

There are a collection of buttons that you can use to link back to your source repository. This lets users browse the repository, or take actions like suggest an edit or open an issue. In each case, they require the following configuration to exist:

html_theme_options = {
...
"repository_url": "https://github.com/{your-docs-url}",
...
}


### Add a button to open issues¶

To add a button to open an issue about the current page, use the following configuration:

html_theme_options = {
...
"repository_url": "https://github.com/{your-docs-url}",
"use_issues_button": True,
...
}


### Add a button to suggest edits¶

You can add a button to each page that will allow users to edit the page text directly and submit a pull request to update the documentation. To include this button, use the following configuration:

html_theme_options = {
...
"repository_url": "https://github.com/{your-docs-url}",
"use_edit_page_button": True,
...
}


By default, the edit button will point to the master branch, but if you’d like to change this, use the following configuration:

html_theme_options = {
...
"repository_branch": "{your-branch}",
...
}


By default, the edit button will point to the root of the repository. If your documentation is hosted in a sub-folder, use the following configuration:

html_theme_options = {
...
"path_to_docs": "{path-relative-to-site-root}",
...
}


You can add a button allowing users to download the currently viewed page in several formats: raw, pdf or ipynb if available. To include this button, use the following configuration:

html_theme_options = {
...
...
}


## Use a single-page version of this theme¶

If your documentation only has a single page, and you don’t need the left navigation bar, then you may configure sphinx-book-theme to run in single page mode with the following configuration:

html_theme_options = {
...
"single_page": True
...
}


By default, your table of contents will begin with the first file that you add to a toctree. You can also configure the theme to show the landing page of the theme in your navigation bar as well.

To add the landing page of your site to the table of contents, use the following configuration:

html_theme_options = {
...
"home_page_in_toc": True
...
}


## Control the left sidebar items¶

You can control what kind of content goes underneath the logo and name of your website in the top left.

To do so, use the html_sidebars variable in your conf.py file. This takes a dictionary of filename patterns as keys, and a list of sidebar elements as values. Any files that match a key will have the corresponding sidebar elements placed in that page’s sidebar.

For example, the following configuration would include only the footer on pages under the posts/ folder:

html_sidebars = {
"posts/*": ["sbt-sidebar-footer.html"]
}


You can also use ** to apply a set of sidebars to all pages of your book. For example:

html_sidebars = {
"**": ["sbt-sidebar-nav.html", "sbt-sidebar-footer.html"]
}


See the Sphinx HTML sidebars documentation for more information.

### Default sidebar elements¶

By default, this theme comes with these three theme-specific sidebar elements enabled on all pages:

• sidebar-search-bs.html: A bootstrap-based search bar (from the PyData Sphinx Theme)

• sbt-sidebar-nav.html: A bootstrap-based navigation menu for your book.

• sbt-sidebar-footer: A configurable snippet of HTML to add to the sidebar (by default it is placed at the bottom).

If you’d like to add a header above a section of TOC links, use :caption: My header text in your toctree directive for that section.

## Customize the logo, title, and favicon¶

You can customize the logo, title, and favicon of your site with the following Sphinx configuration in conf.py:

html_title = "Your title"
html_logo = "path/to/logo.png"
html_favicon = "path/to/favicon.ico"


These will be placed in the top-left of your page.

OpenGraph tags can be used to generate previews and descriptions of your website. These will be automatically generated based on your page’s content and title. However, generating them requires knowing the full URL of your website ahead of time.

To enable metadata tags for your documentation, use the following configuration in conf.py:

html_baseurl = "https://<your-site-baseurl>"


For example, the value of this field for this documentation is:

html_baseurl = "https://sphinx-book-theme.readthedocs.io/en/latest/"


## Control the depth of the left sidebar lists to expand¶

You can control the level of toc items in the left sidebar to remain expanded, using the following configuration in conf.py:

show_navbar_depth = <level>


The default value is 1, which is used in this documentation. Value of 0 will collapse all the sections and sub-sections by default.
