I'm trying to figure out how to calculate all the possible combinations of some given values. there are 3 rows [ ] = Checkboxes 1st: [ ] [ ] [ ] (3 checkboxes total) 2nd: [ ] [ ] [ ] [ ] (4 checkboxes total) 3rd: [ ] [ ] [ ] (3 checkboxes total) rules: 1: It's not possible to keep every checkbox empty, there must be at least 1 checkbox checked on each row. 2: It's also possible to check multiple checkboxes on each row. Example: row 1 [v] [ ] [v] row 2 [v] [v] [ ] [v] row 3 [ ] [v] [ ] How can I calculate every possible combination with these 3 rows, for 1 check per row, or 2 or 3 etc.
