A custom question theme for "Pricing Sliders" in LimeSurvey 3.x

When a slider is manipulated, all of the "higher" sliders are dynamically pushed to higher levels and "lower" sliders are pushed to lower levels. This ensures that the data will always be valid.

Implementation:

1. Extract the download and upload the pricingSliders folder to /pathToLimeSurvey/upload/themes/question/.

2. Create a multiple-numeric-input question, click Save.

3. Set the question setting "Question theme" to "pricingSliders".
   

4. Adjust the question slider settings as necessary (Use slider layout will be defaulted to "On").

5. In the question setting "Randomize sub-question order" field, choose whether to randomize the sub-question order (this replaces the core setting).
   

6. Save question settings.

7. Create subquestions as required.

Notes:

1. Demo survey in /pricingSliders/survey/questions/answer/multiplenumeric/assets/demo/.
