Slider

A control element that allows for a range of selections.

Anatomy

To set up the slider correctly, you'll need to understand its anatomy and how we name its parts.

Each part includes a data-part attribute to help identify them in the DOM.

Examples

Learn how to use the Slider component in your project. Let's take a look at the most basic example:

Range Slider

You can add multiple thumbs to the slider by adding multiple Slider.Thumb

Adding marks

You can add marks to the slider track by using the Slider.MarkerGroup and Slider.Marker components.

Position the Slider.Marker components relative to the track by providing the value prop.

Setting the initial value

To set the slider's initial value, set the defaultValue prop to the array of numbers.

Specifying the minimum and maximum

By default, the minimum is 0 and the maximum is 100. If that's not what you want, you can easily specify different bounds by changing the values of the min and/or max props.

For example, to ask the user for a value between -10 and 10, you can use:

Setting the value's granularity

By default, the granularity, is 1, meaning that the value is always an integer. You can change the step attribute to control the granularity.

For example, If you need a value between 5 and 10, accurate to two decimal places, you should set the value of step to 0.01:

Listening for changes

When the slider value changes, the onValueChange and onValueChangeEnd callbacks are invoked. You can use this to set up custom behaviors in your app.

Changing the orientation

By default, the slider is assumed to be horizontal. To change the orientation to vertical, set the orientation property in the machine's context to vertical.

In this mode, the slider will use the arrow up and down keys to increment/decrement its value.

Don't forget to change the styles of the vertical slider by specifying its height

Changing the origin

By default, the slider's origin is at the start of the track. To change the origin to the center of the track, set the origin prop to center.
