Usage
Full width
If fullWidth
prop is set Button
will take 100% of parent width:
Left and right sections
leftSection
and rightSection
allow adding icons or any other element to the left and right side 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
justify
prop sets justify-content
of 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 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 reduced padding and height.
Gradient variant
When variant
prop is set to gradient
, you can control gradient with gradient
prop, it 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. 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, then use Styles API to modify Button
styles.
Disabled state
To make Button
disabled, set 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 data-disabled
prop instead. Note that disabled styles are the same for all variants.
Disabled state when Button is link
<a />
element does not support disabled
attribute. To make Button
disabled when it is
rendered as a link, set data-disabled
attribute instead and prevent default behavior in
onClick
event handler.
Customize disabled styles
To customize disabled styles, it is recommended to use both &:disabled
and &[data-disabled]
selectors:
&:disabled
is used to style the button whendisabled
prop is set and also when the button is disabled by the parent component (for example, whendisabled
prop is set on a<fieldset />
element which containsButton
).&[data-disabled]
is used to style the button when it is not actually disabled but should look like it is (for example,data-disabled
should be used if you need to use Tooltip with disabledButton
or whenButton
is used as a link)
Disabled button with Tooltip
onMouseLeave
event is not triggered when Button
is disabled, so if you need to use
Tooltip with disabled Button
you need to set data-disabled
prop on Button
instead of disabled
. Note that it is also required to change onClick
event handler to
(event) => event.preventDefault()
as Button
is not actually disabled and will still trigger
onClick
event.
Loading state
When loading
prop is set, Button
will be disabled and Loader with overlay will be rendered
in the center of the button. Loader color depends on Button
variant.
Loader props
You can customize Loader with loaderProps
prop, it accepts all props that
Loader component has:
Styles API
Button
supports Styles API, you can add styles to any inner element of the component withclassNames
prop. Follow 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 data-variant attribute.
Usually new variants are added on theme, this way they are
available in all Button
components in your application.
Customize variants colors
You can customize colors for Button
and other components variants by adding
variantColorResolver to your theme.
autoContrast
Button
supports autoContrast
prop and theme.autoContrast. If autoContrast
is set either on Button
or on theme, content color will be adjusted to have sufficient contrast with the value specified in color
prop.
Note that autoContrast
feature works only if you use color
prop to change background color. autoContrast
works only with 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 component
prop:
You can also use components in component
prop, for example, Next.js Link
:
Polymorphic components with TypeScript
Note that polymorphic components props types are different from regular components – they do not extend HTML element props of the default element. For example,
ButtonProps
does not extendReact.ComponentPropsWithoutRef'<'div'>'
althoughbutton
is the default element.If you want to create a wrapper for a polymorphic component that is not polymorphic (does not support
component
prop), then your component props interface should extend HTML element props, for example:If you want your component to remain polymorphic after wrapping, use
createPolymorphicComponent
function described in this guide.
