ion-range

View Source

The Range slider lets users select from a range of values by moving the slider knob. It can accept dual knobs, but by default one knob controls the value of the range.

Range Labels#

Labels can be placed on either side of the range by adding the slot="start" or slot="end" to the element. The element doesn't have to be an ion-label, it can be added to any element to place it to the left or right of the range.
