Purchasing online in increments

[#1]

Is there a way yet to sell in increments? We sell fabric in meterage, and need to be able to have our customers dictate online how much they want in smaller increments. I know other platforms have this option - quantity (then a drop down menu for whole numbers and a second drop down menu for decimal increments). Example - LikeSew platform. We are finding this to be a huge stumbling block for bridging our online and instore sales.
