I would create a field of type range where the steps would be pre-defined and non-linear (multiple of some number) with html5.
How do I? The code below does not work. Jquery is required? If yes, have examples?
<input type='range' min ='0' max='50' step='15, 20, 26, 36, 50' class='' id='TaxaOportunidade' style=' width: 100%; display: inline; text-align: right;' />
