Bugcrowd design system: Navigation

Guidance last updated: Mar 27, 2023

The main menu for the primary sections or views of the site or application.

Use to allow users to navigate between main sections of the site or app.

Navbar positioning

The navbar is built to sit inside the Header container, which is given a fixed position.

React reference implementations

There are two reference implementations — one for Portal and the other for Tracker.

These are available as React components:

NavbarPortalExample (☞ Portal’s navbar testfile)
NavbarTrackerExample (☞ Tracker’s navbar testfile)

These share the same Navbar component.

Menu contents

The menu contains:

The Bugcrowd ‘hex’ logo as a link to home
A primary navigation, broken up into:
- PrimaryMenuMobile, as a dropdown menu accessible from a hamburger menu panel button, hidden at ≥md breakpoint
- A copy of the menu, displayed only ≥md breakpoints
A user menu grouping, including (if signed-in):
- An icon (bell) link to the user’s notifications + unread marker (Tracker only), which will also display the unread marker if it is passed the string ‘1000+’
- The user’s main dropdown menu (UserMenu), as button holding their avatar

Active/current page or section handling

A LinkItem receives a modifier class if the user is currently on the page for said item. This also applies if the user is deeper within a given top-level section.

You can override/supplement this functionality by setting your own activePathMatcher using regular expressions.

For an example, see the ‘Researchers’ primary menu item defined in NavbarTrackerExample.

Navbar dependencies

- Grid
- Header

Subnav

Guidance last updated: Mar 27, 2023

Rendered example

The secondary menu for sub-sections within a primary navigation section.

Usage

Do not use as a primary navigation.

You can wrap the subnav in a panel. Use the --lined panel variant to retain the bottom border.

Breadcrumbs

Guidance last updated: Mar 27, 2023

Rendered example

A navigational aid which displays the location a user is on within a website’s structure.

Breadcrumb items

The endpoints linked and their order should reflect the hierarchy of the website. That is, the current page a user is on should be the child of a page it was navigable from.

Do not compose breadcrumbs dynamically from a user’s browsing/path history.

Do not make the final breadcrumb — the current page — an anchor. This is to avoid confusion given it would link to the page the user is already on. An alternative would be to use an anchor in conjunction with aria-current="page", however this may still cause confusion.

Do not use breadcrumbs on the top-level page where there would only be the one item, eg the homepage.

Breadcrumb positioning

Breadcrumbs are best positioned within the page’s primary <header> element, when possible.

Breadcrumbs should sit between the primary navigation and the page title.

Visually, breadcrumbs should remain in proximity to primary navigation elements and the page title.

Breadcrumb markup

The breadcrumb container class should be applied on a <nav>, wrapping the list and its items.

Provide the <nav> with an aria-label (eg “Breadcrumb navigation”).

Use ordered lists (<ol>).

Use the --compact and --inline List component for the list styles.

Rendered example of Breadcrumbs

Haml markup example of Breadcrumbs

        Parent
    %li
      Current page

Stepped nav

Guidance last updated: Mar 27, 2023

Rendered example

A linear navigation component used for ordered steps.

List spacing

Use --compact or --spacious accordingly to space lists. See List for more information.

Stepped nav `__step` variants

Use --complete class for completed steps.
Use --current class for the selected step.
Stepped nav anchor accessibility
Use aria-current="step" attribute for the selected step/page.

Handling disabled nav anchor steps

If steps are required to be completed in order and should not be skipped, implementers should disable anchors by setting:

href value to null
aria-disabled="true".
Accordion content for each step

The accordion toggle button is designed to allow the user to expand nested accordions without navigating to each step/page.

When controlling accordion content with the button:

Use aria-controls attribute to link with accordion content
Set aria-expanded attribute to true when the accordion is visible, or false when hidden.

When displaying accordion content:

Set aria-hidden attribute to false to display accordion content, or set to false to hide content.
Assign a unique id to link accordion content with the button.

Checklist assistant

Guidance last updated: Mar 27, 2023

Rendered example

A top-level helper to that gives the user a checklist of actions or tasks.

Use to compose high-level todo lists, such as important tasks for new users.

Avoid using this deeper within a process flow; present this to users in dashboards or top-level indexes.

Checklist assistant item complete variant

Use the --complete item variant for complete[d] checklist items.

Implementers must disable completed anchors by setting their:

href value to null
aria-disabled="true".

Vertical nav

Guidance last updated: Mar 27, 2023

Rendered example
Variants:

--leftactive

Vertical navigation used for third-level navigation.

This navigation uses anchors.

It supports nested lists up to 3 levels deep.

Tertiary nav internals

Current or active item

Set aria-current="page" on the currently active item anchor. This will style the current/active anchor.

A backup .bc-vertical-nav__link--active class is also provided if this is not possible.

Disabled items

If an item anchor is disabled, set aria-disabled="true" on the anchor and omit its href. This will style the disabled anchor.

A backup .bc-vertical-nav--disabled class is also provided if this is not possible.

Adding additional children

Use the provided ‘aside’ class to add content within the anchor, such as spinners or counts.

Small text can also be added, eg. “Unconfigured” for disabled items.

Keep additional content short.

Note: the anchor is a flex container so consider wrapping nested sibling text nodes in span tags.

Tertiary nav placement

Place the tertiary nav left to the main content space (eg. inside a sidebar).

If the tertiary nav is placed to the right of the main content space, append the --leftactive container variant to flip the active and hover bar effect to the left.

Tabbed nav

Guidance last updated: Mar 27, 2023

Rendered example

Tabs help switch between different sets of content at the same level of hierarchy.

Use to provide more visibility of sub sections of content there are in a page rather than dropdowns.

Tabbed navs stay at the top of the content container and control the content beneath it.

Do not use this pattern if users need to see multiple tabbed content sections simultaneously (cf. Accordions).

Using Tabbed navs

The first tab should be “active” by default — it should be the most important or relevant tab
Use simple and short labels
Avoid disabling any tab(s) — this is confusing to end users
Avoid long sets of tabs as they will wrap poorly at ≥md viewport breakpoint
Do not mix anchor and button tabs in the same tabbed nav

Tabbed navs and JavaScript

Use JavaScript to dynamically change the active tab and its contents.

Two methods exist, using:

Anchors, for:
- Separate web pages/endpoints
- Content regions already existing on the page, linking each respective content container’s ID
Buttons for dynamic loading and/or hidding of content regions into the DOM.

When using anchors to link to other web pages set aria-current="page" on the current/selected anchor. Wrap the anchor list in a <nav>.

When using Javascript with either anchors or buttons to dynamically toggle tab content without page refreshes:

Set role="tablist" on the list
On each “Tab”:
- Set role="tab" on each anchor or button
- Set aria-controls on each anchor or button, linking its respective tabpanel ID
- When using buttons, set the aria-selected boolean
- When using anchors, set aria-current="true" on the current/selected tab.
On each “Tab panel”/content region:
- Set role="tabpanel" on each content region
- Set hidden on non-active content regions.

This is not required by using <button>s for dynamic route changes.

Usage guidance adapted from GOV.UK’s Tabs Design System entry and Chakra UI’s Tabs component.

Pagination

Guidance last updated: Mar 27, 2023

Rendered example

Use pagination controls to provide navigation for content that is paginated.

The pagination pattern has two functions:

As an interactive navigation
As an indicator of where the user is within the paginated list index, providing via <output>:
- the current range of items presented on the page;
- from the total number of items in the paginated index.

Pagination usability and accessibility

While <ol> would be suitable here given the linearity implied, use un-ordered lists (<ul>).

Non-visual assistive technologies (eg screen readers) commonly preface <ol> list items with their lexical position. This results in first announcing the lexical count of the list item, which will not align with the page count due to the [ellipsis] range indicators, and the First/Last/Prev/Next, controls.

Set aria-current="true" for the current numbered page anchor — this should also apply to the “First” and “Last” anchors when on those pages.

Set aria-hidden="true" on the list items that contain the range indicators, as these are entirely superfluous — and may cause confusion — to non-visual users. This does not visually hide the element.

Omit the jump control links — first/prev and next/last — when on the first and last page of listings respectively.

Provide a maximum of three pages prior to and after the current page; do not list every possible page.

Pagination in Single Page Applications

Use <button>s when paginating in a single page application.

Use ARIA to provide context for the navigation controls:

menubar role on the wrapping container, replacing or overriding the implicit <nav> role
menu role on the top-level wrapping <ul>
menuitem roles for the first/last and prev/next buttons
menuradioitem role for each numbered page button
aria-checked for the current numbered page button — this should also apply to the “First” and “Last” buttons when on those pages
aria-setsize for each numbered page button giving the total number
aria-posinset for each numbered page button giving its lexical position within the set.

Guidance last updated: Mar 27, 2023

Visually-hidden ‘skip-links’ that are keyboard accessible.

Use to provide keyboard-accessible jump points to main sections of a page.

Typically skip-links link users to

Main navigation (the primary <nav>)
Main content container (eg <main>)

The links are established by pointing to the ID for each endpoint.

Avoid ID collisions: Ensure the page content ID does not conflict with the ID the Modals rely on.

Testing the rendered example: Skip-to links are visually hidden until they receive focus. Use the keyboard by pressing Tab to bring the links into :focus.

Visual location of skip-links: Upon receiving :focus, skip-to links will always visually appear to the top left of the page, layered at the ‘overlay’ z-index context layer.
