Navigation

Global navigation

Vanilla includes a simple navigation bar that you can add to the top of your sites.

The navigation items are collapsed behind a "Menu" link in small screens and displayed horizontally on larger screens.

The navigation pattern is one of the first patterns to implement the new theming architecture in Vanilla. The default is light. But, to switch to a dark navigation, you can either:

• Override the value of the $theme-default-nav in _settings_themes.scss to dark
• Add a state class to the p-navigation class: is-dark when the default navigation is light, or is-light when the default has been changed to dark

You can also manually override the background color of the navigation using the variable $color-navigation-background. If the lightness of the background is above 70%, the text colour will switch to dark to improve readability.

You can change the breakpoint at which the menu changes to a small screen menu by adjusting the $breakpoint-navigation-threshold in _settings_breakpoints.scss.

Deprecated

In Vanilla 2.8 we deprecated the use of p-navigation__links, p-navigation__link and classless <a> in the navigation. Support for these classes will be removed in future version 3.0.

You should use p-navigation__items, p-navigation__item and <a class="p-navigation__link"> instead.

To update to new class names:

• rename all occurrences of p-navigation__links to p-navigation__items
• rename all occurrences of p-navigation__link to p-navigation__item
• add p-navigation__link class to all <a> elements that are direct child of p-navigation__item

Dropdown

Drop-down menus can be added to the navigation by including one or more p-navigation__item--dropdown-toggle components.

To open the dropdown you need to set the is-active class on p-navigation__item--dropdown-toggle element, but also set aria-hidden to false on p-navigation__dropdown.

By default, dropdowns are left-aligned with their parent; if you'd prefer the menu to be positioned from the right, use the p-navigation__dropdown--right modifier. This can be seen in the "My account" menu in the example.

Sub-navigation

Deprecated

.p-subnav is now deprecated, it and its associated child elements can be updated simply by substituting the following class names:

Side navigation

The side navigation pattern can be used to provide more detailed navigation alongside your content.

It allows grouping the links into navigation sections and nesting them up to three levels.

Current page in the side navigation should be highlighted by adding aria-current="page" attribute to the corresponding p-side-navigation__link element. Alternatively, if aria-current attribute cannot be set, the is-active class can be used instead.

Use p-side-navigation__status inside p-side-navigation__link elements to add status labels or icons on right side of navigation items.

Icons

To add icons on the left side of the items in side navigation use the .p-side-navigation--items class.

Sticky

On pages with content significantly longer than the side navigation contents you can make the navigation sticky to keep it visible when scrolling by adding .is-sticky class to the root element of .p-side-navigation.

Raw HTML

When the HTML markup of the side navigation links is generated by an external service and Vanilla class names cannot be added to the elements, use the p-side-navigation--raw-html modifier.

In this variant, the side navigation pattern will style headings (h2, h3, etc.) and lists (ul, li) with links or text elements (a, strong, span) consistently with default side navigation component:

• headings (h2, h3, etc.) get the styling of p-side-navigation__item--title
• lists: ul tags are styled as p-side-navigation__list, and li tags as p-side-navigation__item
  • nesting lists (ul > li > ul > li ...) is possible up to 3 levels
• text elements (span, strong) inside li are styled as p-side-navigation__text
• links (a) inside li are styled as p-side-navigation__link
  • is-active class needs to be added to a link element to mark the active page

Because of the limitations of raw HTML markup without class names, it's not possible to use icons or status labels in the raw HTML variant of side navigation.

JavaScript functionality

On small screens side navigation is rendered off-screen as a drawer. To open the side navigation drawer, add is-expanded class to main .p-side-navigation element. To close the drawer (with the animation) remove is-expanded class and replace it with is-collapsed class.

To make sure side navigation toggle works without JavaScript the toggle button for opening the side navigation drawer should be an anchor with href attribute pointing to the id attribute of the side navigation element (for example: <a href="#drawer" class="p-side-navigation__toggle">).

Application layout

For applications built with the application layout the size and positioning of the navigation panel is handled by the layout itself, so the side navigation component doesn't need it's own drawer, overlay or toggle buttons.

To use side navigation in the application place .p-side-navigation--icons in the l-navigation element. You don't use p-side-navigation__toggle, p-side-navigation__overlay or p-side-navigation__drawer elements, just put the lists of the links p-side-navigation__list as direct children of .p-side-navigation element.

Additionally, in order for application layout to fully control side navigation elements when expanding and collapsing you need to wrap the text of the side navigation items in <span class="p-side-navigation__label">. This will allow to fade them out when navigation collapses.

For more information, read the dedicated application layout documentation.

Theming

The side navigation is available in a light and a dark theme. The colours used by both themes in the colour settings file. Overriding the colours of individual elements of the side navigation is discouraged, as this may lead to accessibility issues, or inconsistencies with other components that use the same theme.

By default, the side navigation uses the light theme. To change the global default, set $theme-default-p-side-navigation to dark.

To change the appearance of an individual instance of the side navigation, you can use the is-dark class.

For more details about themes in Vanilla refer to the Color theming section of the documentation.

See example of side navigation with dark theme.

Import

To import just navigation or sub-navigation component into your project, copy snippets below and include it in your main Sass file.

@import 'patterns_navigation';
@include vf-p-navigation;

// sub-navigation is optional you can include it alongside navigation component
@import 'patterns_subnav';
@include vf-p-subnav;

To import side navigation, copy snippet below:

@import 'patterns_side-navigation';
@include vf-p-side-navigation;

// optionally add icons and/or labels if you use them in side navigation__nav
@import 'patterns_label';
@include vf-p-label;

@import 'patterns_icons';
@include vf-p-icons;
