Button

A grommet Button is used for anything that looks like a button on the screen. If an href is provided, it will be rendered in the DOM with <a/>. An Anchor component should be used for inline anchors within textual contexts.

In May 2020, we enhanced Button to have three kinds, outlined below. In order to maintain backwards compatibility, this approach is only available when the theme being used defines button.default.

default

The majority of Buttons on the page. Their affordance is primarily driven by their context, in a Nav in a Header or Sidebar, the corner of a tile or card, etc.

primary

The primary call to action. There should typically be at most one primary Button on the screen. In a Form context, it signifies the action bound to the enter key that will submit the form.

secondary

When there isn’t enough context to indicate its affordance, or when it should call extra attention to itself but isn’t the primary call to action, use a secondary Button. Secondary buttons are only available when the underlying theme being used defines button.default.

Props

a11yTitle

Custom label to be used by screen readers. When provided, an aria-label will be added to the element.

string

"a user friendly label for screen readers"

active

Whether the button is active.

boolean

true

false

alignSelf

string

"start"

"center"

"stretch"

as

The DOM tag or react component to use for the element.

string

The name of a component.

"div"

function

badge

An indicator to show on the top-right of the Button. For accessibility, supplement the badge by adding an a11yTitle to the Button which provides a useful message to screen readers. For example, "2 unread notifications".

boolean

When badge is a boolean, the badge will be a circle with background color 'brand'.

true

false

element

<Box>...</Box>

number

When badge is a number, that number will appear inside the badge.

object

When badge is an object, background refers to the background color of the badge, value refers to either the numeric value that appears within the badge or a boolean if background has been defined on the object but no numeric content is desired, and max refers to the max value that can appear inside the badge. For example, if value is 10 and max is 9, the content in the badge will be displayed as 9+.


{
  background: {
    color: "...",
    dark: "...",
    image: "string",
    position: "string",
    opacity: "...",
    repeat: "...",

React/DOM Properties

At its core, the Button component is a regular <button> element. Thus, both DOM and React properties, methods, and events are accessible. To read up on all of the possible DOM attributes and types available for button elements, check out this MDN Web Documents page. To learn more about DOM events and methods, you can read more on the MDN Web Events documentation page.

Also, feel free to read about the types of React events available, or see how DOM attributes change in React. Working in tandem with Styled Components, you also have access to the as property.
