value	number	0	Stepper value
min	number	0	Minimum value
max	number	100	Maximum value
step	number	1	Maximum value
wraps	boolean	false	When enabled, incrementing beyond maximum value sets value to minimum value; likewise, decrementing below minimum value sets value to maximum value
autorepeat	boolean	false	When enabled it will repeatedly increase/decrease values while you tap and hold plus/minus buttons
autorepeatDynamic	boolean	false	When enabled it will increase autorepeat ratio based on how long you hold the button
input	boolean	true	Defines should it render `<input>` element or not
inputReadonly	boolean	false	Makes inner input element `readonly`
buttonsOnly	boolean	false	Disables inner value container between stepper buttons
formatValue	function(value)		Custom function to format value for value element between buttons. It must return new formatted value
manualInputMode	boolean	false	Enables manual input mode. This mode allows to type value from keyboar and check fractional part with defined accurancy. Also, `step` parameter is ignored when typing in this mode.
decimalPoint	number	4	Number of digits after dot, when in manual input mode.
buttonsEndInputMode	boolean	true	Disables manual input mode on Stepper’s minus or plus button click.
disabled	boolean	false	Defines whether the stepper is disabled or not
round	boolean	false	Makes stepper round
roundIos	boolean	false	Makes stepper round for iOS theme only
roundMd	boolean	false	Makes stepper round for MD theme only
big	boolean	false	Makes big stepper
bigIos	boolean	false	Makes big stepper for iOS theme only
bigMd	boolean	false	Makes big stepper for MD theme only
small	boolean	false	Makes small stepper
smallIos	boolean	false	Makes small stepper for iOS theme only
smallMd	boolean	false	Makes small stepper for MD theme only
fill	boolean	false	Makes stepper filled color
fillIos	boolean	false	Makes stepper filled color for iOS theme only
fillMd	boolean	false	Makes stepper filled color for MD theme only
raised	boolean	false	Makes stepper raised. Affects MD theme only
