My survey has a question with a text array where the first column (x-axis subquestion) is supposed to be a date. Ideally, I would like to have a date picker for each cell in my date column. Unfortunately, none of the code examples I could find in this forum to modify the cell behavior work with LS 3.x. Second best would be a regexMatch for something like this:
([12]\d{3}-(0[1-9]|1[0-2])-(0[1-9]|[12]\d|3[01]))
Here again, I spent hours looking at various topics on similar subjects without finding a solution. I would very much appreciate some help on this (either datepicker or validation).
