Range

sl-range

Ranges allow the user to select a single value within a given range using a slider.

Examples

Basic Range 

<sl-range></sl-range>

sl-range

Labels

Use the label attribute to give the range an accessible label. For labels that contain HTML, use the label slot instead. 

<sl-range label="Volume" min="0" max="100"></sl-range>

sl-range label="Volume" min="0" max="100"

Help Text

Add descriptive help text to a range with the help-text attribute. For help texts that contain HTML, use the help-text slot instead. 

<sl-range label="Volume" help-text="Controls the volume of the current song." min="0" max="100"></sl-range>

sl-range label="Volume" help-text="Controls the volume of the current song." min="0" max="100"

Min, Max, and Step

Use the min and max attributes to set the range’s minimum and maximum values, respectively. The step attribute determines the value’s interval when increasing and decreasing. 

<sl-range min="0" max="10" step="1"></sl-range>

sl-range min="0" max="10" step="1"

Disabled

Use the disabled attribute to disable a slider.

<sl-range disabled></sl-range>

sl-range disabled=true

Tooltip Placement

By default, the tooltip is shown on top. Set tooltip to bottom to show it below the slider. 

<sl-range tooltip="bottom"></sl-range>

sl-range tooltip="bottom"

Disable the Tooltip

To disable the tooltip, set tooltip to none.

<sl-range tooltip="none"></sl-range>

sl-range tooltip="none"

Custom Track Colors

You can customize the active and inactive portions of the track using the --track-color-active and --track-color-inactive custom properties. 

<sl-range
  style="
  --track-color-active: var(--sl-color-primary-600);
  --track-color-inactive: var(--sl-color-primary-100);
"
></sl-range>

sl-range[style="
  --track-color-active: var(--sl-color-primary-600);
  --track-color-inactive: var(--sl-color-primary-100);
"]

Custom Track Offset

You can customize the initial offset of the active track using the --track-active-offset custom property. 

<sl-range
  min="-100"
  max="100"
  style="
  --track-color-active: var(--sl-color-primary-600);
  --track-color-inactive: var(--sl-color-primary-100);
  --track-active-offset: 50%;
"
></sl-range>

sl-range[min="-100" max="100" style="
  --track-color-active: var(--sl-color-primary-600);
  --track-color-inactive: var(--sl-color-primary-100);
  --track-active-offset: 50%;
"]

Custom Tooltip Formatter

You can change the tooltip’s content by setting the tooltipFormatter property to a function that accepts the range’s value as an argument. 

<sl-range min="0" max="100" step="1" class="range-with-custom-formatter"></sl-range>

<script>
  const range = document.querySelector('.range-with-custom-formatter');
  range.tooltipFormatter = value => `Total - ${value}%`;
</script>

sl-range.range-with-custom-formatter min="0" max="100" step="1"

javascript:
  const range = document.querySelector(.range-with-custom-formatter);
  range.tooltipFormatter = value => `Total - ${value}%`;
