Hi!
I wanted to include sliders in my survey with hidden handle by default until user clicks on the slider.
Thanks to Tony's solution found here (
www.limesurvey.org/de/forum/can-i-do-thi...ser-clicks-on-slider
) I was able to do so.
Playing with that approach I found a significant drawback which I would love to solve:
1. Just imagine you have a question containing 20 mandatory sliders.
2. A participant answers 19 sliders but accidentally misses a single one.
3. After clicking "Next" the mandatory error message appears (with the page reloaded).
4. Now all sliders are hidden again (even the sliders already answered), so the participant thinks s(he) has to answer all sliders again (which is not the case as the values have been stored).
Any ideas how to circumvent that behaviour, e. g. by
- showing the handles of the sliders already answered or
- hiding those answered sliders completely or
- deactivating the "next"-button until ALL sliders have been answered or
- ...?
Thanks in advance!
