Usage
Full width
If the fullWidth prop is set, the Button will take 100% of the parent width:
Left and right sections
leftSection and rightSection allow adding icons or any other element to the left and right sides of the button.
When a section is added, padding on the corresponding side is reduced.
Note that leftSection and rightSection are flipped in RTL mode
(leftSection is displayed on the right and rightSection is displayed on the left).
Sections position
The justify prop sets the justify-content of the inner element. You can use it to change the alignment of
left and right sections. For example, to spread them across the button, set justify="space-between".
If you need to align just one section to the side of the button, set justify to space-between
and add an empty <span /> to the opposite section.
Compact size
Button supports xs – xl and compact-xs – compact-xl sizes. compact sizes have
the same font size as xs – xl but with reduced padding and height.
Gradient variant
When the variant prop is set to gradient, you can control the gradient with the gradient prop, which accepts an object with from, to and deg properties. If thegradient prop is not set, Button will use theme.defaultGradient which can be configured on the theme object. The gradient prop is ignored when variant is not gradient.
Note that variant="gradient" supports only linear gradients with two colors. If you need a more complex gradient, use the Styles API to modify Button styles.
Disabled state
To make a Button disabled, set the disabled prop. This will prevent any interactions with the button
and add disabled styles. If you want the button to just look disabled but still be interactive,
set the data-disabled prop instead. Note that disabled styles are the same for all variants.
Disabled state when Button is link
The <a /> element does not support the disabled attribute. To make a Button disabled when it is
rendered as a link, set the data-disabled attribute instead and prevent default behavior in the
onClick event handler.
Customize disabled styles
To customize disabled styles, it is recommended to use both &:disabled and &[data-disabled]
selectors:
&:disabledis used to style the button when thedisabledprop is set and also when the button is disabled by the parent component (for example, when thedisabledprop is set on a<fieldset />element which contains theButton).&[data-disabled]is used to style the button when it is not actually disabled but should look like it is (for example,data-disabledshould be used if you need to use Tooltip with a disabledButtonor when theButtonis used as a link)
Disabled button with Tooltip
The onMouseLeave event is not triggered when a Button is disabled, so if you need to use a
Tooltip with a disabled Button, you need to set the data-disabled prop on the Button
instead of disabled. Note that it is also required to change the onClick event handler to
(event) => event.preventDefault() as the Button is not actually disabled and will still trigger the
onClick event.
Loading state
When the loading prop is set, the Button will be disabled and a Loader with overlay will be rendered
in the center of the button. Loader color depends on the Button variant.
Loader props
You can customize the Loader with the loaderProps prop, which accepts all props that the
Loader component has:
Styles API
Button supports the Styles API; you can add styles to any inner element of the component with the classNames prop. Follow the Styles API documentation to learn more.
Component Styles API
Hover over selectors to highlight corresponding elements
Example of customizing Button with Styles API and data-* attributes:
Custom variants
To add new Button variants, use the data-variant attribute.
Usually new variants are added to the theme, this way they are
available in all Button components in your application.
Customize variant colors
You can customize colors for Button and other component variants by adding
variantColorResolver to your theme.
autoContrast
Button supports the autoContrast prop and theme.autoContrast. If autoContrast is set either on Button or on the theme, the content color will be adjusted to have sufficient contrast with the value specified in the color prop.
Note that the autoContrast feature works only if you use the color prop to change the background color. autoContrast works only with the filled variant.
Button.Group
Note that you must not wrap child Button components with any additional elements:
Button.GroupSection
Use Button.GroupSection component to render sections that are not buttons inside Button.Group:
Polymorphic component
Button is a polymorphic component – its default root element is button, but it can be changed to any other element or component with the component prop:
You can also use components in the component prop, for example, Next.js Link:
Polymorphic components with TypeScript
Note that polymorphic component prop types are different from regular components – they do not extend HTML element props of the default element. For example,
ButtonPropsdoes not extendReact.ComponentProps'<'div'>'althoughbuttonis the default element.If you want to create a wrapper for a polymorphic component that is not polymorphic (does not support the
componentprop), then your component props interface should extend HTML element props, for example:If you want your component to remain polymorphic after wrapping, use the
polymorphicfunction described in this guide.
