Header

This component renders a responsive, Canvas-style header.

Usage

import * as React from 'react';
import {Header} from '@workday/canvas-kit-labs-react-header';
import {AvatarButton} from '@workday/canvas-kit-react-avatar';
import {IconButton} from '@workday/canvas-kit-react-button';
import {notificationsIcon} from '@workday/canvas-system-icons-web';
import {Button} from '@workday/canvas-kit-react-button';

<Header title="Header" brandUrl="#">
  <nav>
    <ul>
      <li className="current">
        <a href="#">Discover</a>
      </li>
      <li>
        <a href="#">Library</a>
      </li>
      <li>
        <a href="#">Create</a>
      </li>
      <li>
        <a href="#">Manage</a>
      </li>
    </ul>
  </nav>
  <IconButton
    icon={notificationsIcon}
    variant={IconButton.Variant.Circle}
    title="Notifications"
    aria-label="Notifications"
  />
  <AvatarButton
    onClick={() => {
      alert('clicked avatar');
    }}
    altText="Profile"
  />
  <Button variant={Button.Variant.Primary}>Sign Up</Button>
</Header>;

Special Children

nav, ul, li

For a semantic navigation menu, this component will style a child <nav> element with an un-ordered list inside (<ul>). This list can contain any number of <li> elements with <a> elements. You can visually distinguish the link that your page is currently on by adding the class name: "current" to the <li> element containing the current page link.

SystemIcon

Deprecated (but supported) - please use IconButton instead.

The Header supports Canvas SystemIcon components, but will convert them into an IconButton with the correct styling for the theme you've provided.

A Note About Buttons

Please use a Primary Canvas Button for this component's call-to-action buttons (see the usage example below).

Static Properties

Theme: HeaderTheme

<Header title="Blue Header" themeColor={Header.Theme.Blue} />

Variant: HeaderVariant

<Header title="Marketing Header" variant={Header.Variant.Full} />

Component Props

Required

None

Optional

title: string

The title displayed on the header next to the logo.

Default: ''

themeColor: HeaderTheme

The theme of the header (White, Blue, or Transparent).

Default: HeaderTheme.White

variant: HeaderVariant

Specifies the variation of the header.

Default: HeaderVariant.Dub

brandUrl: string

The href attribute when clicking on the title logo. Default: '#'

brand: React.ReactNode

If specified, this replaces the contents of the Dub logo and title. Used for replacing Dub + title with a contained lockup and/or for adding custon design elements next to the Dub + title lockup.

Default: DubLogoTitle (for "Dub" variants) or WorkdayLogoTitle (for "Full" variants)

breakpoints: { sm: number, md: number, lg: number }

The min-width breakpoints at which to collapse the children of the header.

Special children collapse in this order:

• The nav element collapses into a hamburger icon menu after the screen width falls below the lg breakpoint
• Any IconButton or SystemIcon collapses after the screen width falls below the md breakpoint
• sm may be reserved for future functionality

Default:

{
  sm: 320,
  md: 768,
  lg: 1120,
}

onMenuClick: (React.SyntheticEvent) => void

A click handler for when the user clicks the mobile collapsed nav icon.

centeredNav: boolean

When true, the header centers the nav in the middle of the header.

onSearchSubmit: (React.SyntheticEvent) => void

A function that accepts a React.SyntheticEvent for when the user submits from the search input. A search input will not be rendered if this is not provided.

highlightSearch: boolean

A flag to highlight the search on the left beside the logo. Will only work if onSearchSubmit is provided.

onBreakpointChange: (BreakpointType | string) => void

If specified, this callback is executed after the screen size changes with the new breakpoint key. It also gets called on initialization so the consumer has the original breakpoint

Global Header

The Global Header (or App Header) is used for Workday applications.

Usage

import {AvatarButton} from '@workday/canvas-kit-react-avatar';
import {GlobalHeader, DubLogoTitle} from '@workday/canvas-kit-labs-react-header';
import {Avatar} from '@workday/canvas-kit-react-avatar';
import {IconButton} from '@workday/canvas-kit-react-button';
import {notificationsIcon, inboxIcon} from '@workday/canvas-system-icons-web';

const HeaderBrand = () => <DubLogoTitle themeColor={Header.Theme.White} />
const HeaderAvatar = () => <AvatarButton onClick={handleMenuClick} url="https://my.cdn.amazonaws.com/assets/avatar_pic.png" />
const handleSearchSubmit = query => console.log("Submitted query: ", query)
const openMenu = e => console.log("Menu opened")
const handleBreakpointChange = key => console.log(`Breakpoint change: ${key}`)

/**
 * In this instance, the right-most child will be an AvatarButton component, when the GlobalHeader
 * shrinks below the specified breakpoint (720 in this case), the children get replaced by a menuToggle.
 * For most GlobalHeader implementations, the menuToggle is also the AvatarButton component.
 */
<GlobalHeader
  brand={<HeaderBrand />}
  menuToggle={<HeaderAvatar />}
  onMenuClick={openMenu}
  onSearchSubmit={handleSearchSubmit}
  breakpoint={720}
  onBreakpointChange={handleBreakpointChange}
>
  <IconButton icon={notificationsIcon} variant={IconButton.Variant.Circle} />
  <IconButton icon={inboxIcon} variant={IconButton.Variant.Circle} />

A click handler for when the user clicks the menuToggle element.

"Dub" Logo and Title

Usage

import {Header, DubLogoTitle} from '@workday/canvas-kit-labs-react-header';
import {colors} from '@workday/canvas-kit-react-core';

<Header
  brand={<DubLogoTitle title="This title will show up instead" bgColor={colors.blueberry600} />}
