Navigation

Help the user navigate your website using configurable navigation elements.

Hinode supports several types of navigation that utilize Bootstrap elements. The main navigation is positioned on the top of the screen and includes a search input element. An optional secondary navigation is available as sidebar. Next to these navigation items, pages may optionally include a breadcrumb to indicate the current page’s location within the site’s navigational hierarchy. Finally, pages may also include a table of contents element that is linked to the scroll position of the current page.

Basic configuration

The basic configuration of the navigation elements is set in the navigation section of the site parameters. The folllowing settings are supported:

The below configuration shows the default configuration set in config/_default/params.toml.

• /config/_default/params.toml

[navigation]
    logo = "/img/logo_icon.svg"
    color = "body"
    fixed = true
    offset = "4em"
    search = true
    breadcrumb = false
    toc = true
    sidebar = true

Main navigation

The main navigation uses Hugo’s menu system to generate a responsive navigation bar at the top of the page. The navigation bar uses a breakpoint to add a toggler for smaller screens. A language switcher is added automatically if your site supports multiple languages. The language switcher links to the currently translated page if available.

Menus

The navigation bar uses Hugo’s menu system to generate the menu items. The navigation supports nesting at one level depth. The following example defines an example menu configuration called sample (the main configuration is called main).

• /config/_default/menus/menus.en.toml

[[sample]]
  name = "Blog"
  url = "/blog/"
  weight = 10

[[sample]]
  name = "Projects"
  url = "/projects/"
  weight = 20

[[sample]]
  name = "Sample project"
  url = "/en/projects/sample-project/"
  parent = "Projects"
  weight = 1

[[sample]]
  name = "Another project"
  url = "/en/projects/another-project/"
  parent = "Projects"
  weight = 2

Example

Using the sample configuration defined in the previous paragraph, the navigation bar looks like this:

Customization

Hinode includes a navigation bar at the top of the screen by default. You can modify the configuration in the layouts/_default/baseof.html file. The navigation bar is also available as shortcode.

Sidebar navigation

Hinode supports optional sidebar navigation. It is intended to be used as companion to the main navigation and is typically used in content-heavy sections, such as documentation pages. On smaller screens, the sidebar is replaced with an offcanvas element. In this case, the main navigation receives an additional toggler on the left of the screen.

Menus

Inspired by Bootstrap’s documentation site, Hinode uses a separate configuration file for the sidebar menus. A sidebar can be configured for each main section of the site. For example, the sidebar menus of the Docs section are defined in data/docs.yml. The menus support group items and single page items. Below example defines a group section called Getting started with three siblings. A single page About is added next.

- title: Getting started
  pages:
    - title: Introduction
    - title: Commands
    - title: Contribute
- title: About

An entry in the page’s frontmatter is needed to link the page to the correct entry in the sidebar. Below example highlights the relevant frontmatter elements from the Introduction page, which is part of the Getting started group. Please notice the group name needs to be defined in kebab-case, e.g. getting-started. You can omit the group name for single page entries, such as the About page in the example configuration above.

---
title: Introduction
group: getting-started
---

Customization

The file assets/scss/components/_sidebar.scss contains the styling of the sidebar. It refers to a button $btn-toggle that is defined in assets/scss/common/_icons.scss. It also defines the spacing to be added to the page’s main content section when using a fixed navigation bar:

• /assets/scss/components/_sidebar.scss

.sidebar {
    top: $navbar-offset;
}

.sidebar-item {
    color: black;
}

.btn-toggle {
    padding: 0.25rem 0.5rem;
    font-weight: 600;
    color: rgba(0, 0, 0, 0.65);
    background-color: transparent;

    &:hover,
    &:focus {
        color: black;
        background-color: tint-color($primary, 90%);
    }

    &::before {
        width: 1.25em;
        line-height: 0;
        content: $btn-toggle;
        transition: transform 0.35s ease;
        transform-origin: 0.5em 50%;
    }
}

.btn-toggle[aria-expanded="true"] {
    color: black;

    &::before {
        transform: rotate(90deg);
    }
}

.btn-toggle-nav a {
    padding: 0.1875rem 0.5rem;
    margin-top: 0.125rem;
    margin-left: 1.25rem;

    &:hover,
    &:focus {
        background-color: tint-color($primary, 90%);
    }

    &.active {
        font-weight: bold;
    }
}

@if $enable-dark-mode {
    @include color-mode(dark) {
        .sidebar-item {
            color: var(--bs-tertiary-color);
        }

        .btn-toggle {
            color: var(--bs-tertiary-color);
        
            &:hover,
            &:focus {
                color: $secondary;
                background-color: tint-color($primary, 90%);
            }
        
            &::before {
                content: $btn-toggle-dark;
            }
        }

        .btn-toggle[aria-expanded="true"] {
            color: var(--bs-secondary-color);
        }

        .btn-toggle-nav a {
            padding: 0.1875rem 0.5rem;
            margin-top: 0.125rem;
            margin-left: 1.25rem;

            &:hover,
            &:focus {
                color: $secondary;
                background-color: tint-color($primary, 90%);
            }

            &.active {
                font-weight: bold;
            }
        }
    }
}

Breadcrumb

Hinode supports optional breadcrumb navigation. The breadcrumb indicates the current page’s location within the site’s navigational hierarchy. It is automatically populated by Hugo. Enable the breadcrumb in the basic navigation configuration. If enabled, all single pages will add breadcrumb navigation to the top of the page.

Example

When enabled, the breadcrumb looks like this:

Customization

The breadcrumb is also available as shortcode.

Table of contents

Single pages can optionally show an table of contents on the right of the screen. The table of contents is automatically popuplated based on the headings within the page content (two levels deep). The table of contents is hidden on smaller screens or if it has less than two items. Enable the table of contents in the basic navigation configuration. If enabled, all single pages will show the element, unless disabled in the page’s frontmatter.

Customization

The file assets/scss/components/_toc.scss defines the styling of the table of contents element. It adds spacing to align the element to the sidebar, amongst other styling:

• /assets/scss/components/_toc.scss

.toc {
    grid-area: toc;
    right: 0;
    z-index: 2;
    height: calc(100vh - 7rem);
    overflow-y: auto;
    top: $navbar-offset;
}
