    • false the track will render without a bar.
    valueArray<number>
    | number

    The value of the slider. For ranged sliders, provide an array with two values.

    valueLabelDisplay'auto'

    Controls when the value label is displayed:

    • auto the value label will display when the thumb is hovered or focused.

    • off will never display.
    valueLabelFormatfunc
    | string    		function Identity(x) { return x; }

    The format function the value label's value.
    When a function is provided, it should have the following signature:
    - {number} value The value label's value to format - {number} index The value label's index to format

    The ref is forwarded to the root element.
