yes this is long waited feature and would be nice to have!

defiantly need it to be more competitive to other platforms that already offer this feature to make their forms more appealing

Definitely need this, such a basic function that is provided by most form/survey builders. Surprised that it is still lacking.

We have found that incorporating numeric sliders into our lead generation forms has greatly improved user engagement and lead quality with different form builder. By providing an interactive and user-friendly interface, we have been able to capture more accurate information from our prospects, leading to more successful conversions.

Please consider this in GHL.
