[!] Your opinion: is slider item needed for form?

If you are using dhtmlxForm, please leave a comment whether you need or do not need a slider item. If yes, for what purposes?
Your feedback will be much appreciated

Hello,

IMHO, dhtmlxSlider would be great. If you have a form where you need to change some values in a group where the sum of 4 input values cannot be greather than 100%, dhtmlxSlider will be a way to do not permit user type incorrect values here.

By the way, I was looking for this yesterday. I need to put a input on a dhtmlxForm to user inform something to me. The right component to what I mean is dhtmlxSlider.

In the attachment, I put something that will be possible using dhtmlxSlider in a dhtmlxForm.
