I have Machform 4.8 and am am wondering why it is that "Enable Choice Limit" is available for Multiple Choice and Dropdowns but not for Checkboxes. The use of the choice limit for dropdowns and multiple choice fields is very limited as it does not allow for users to select more than one item per submission. If it were applied to checkboxes we could for instance set up a field where only 10 units of a certain item were available and indicate this by having 10 checkboxes in the field numbered 1-10. Each checkbox would have a choice limit of 1 set and would either disappear or be grayed out after selection (preferably grayed out but showing the tick), indicating that it was no longer available.
This feature is available in the online form builders 123 Contact Form and Wufoo and it would be great to see it implemented in Machform. Incidentally while looking at Wufoo I did notice a striking similarity to the Machform system. I wonder if it has been based on this?
