I love the slider layout of multiple numerical input. How ever a user asked me if it would be possible to have an option to automatically adjust the slider for answer x and y, when the user changes the answer for z.

E.g.
equals sum set to 30.
initial sum for x, y, z is 10.

• The respondent changes the value of x to 14.
• The system automaticcally changes y and z to be 8.
• The repsondent then changes the value of x again. This time to 13.
• The system automaticcally changes y and z to be 8.5.
• The respondent now changes the value of y to 10
• The system either
• ----a) assumes that x is set, and therefore changes z to 7
• ----b) changes x to 12.25 and changes z to 7.75

I am not completely sure that this would always be simpler, but a user asked me for this feature. What do you think?

Sincerely

I think it can be done but it requires some customized Javascript code which is not that trivial I guess.

Nice - it's not that important for me right now, it was just something I was asked about.

I am just as much interested in wether people think this is a good idea?

EDIT: So I guess I should add it to ideas.limesurvey.org
