Hi, Mr_Zylinder,
this is really easy.
As I wrote before:
Use a "multiple numericl input" question.
In the advanced settings you find the slider options.
Just set "Use slider" to "On" and the appropiate min and max values.
To separate your items of the left and right end of the slider the pipe-symbol is the default.
Now in "Edit subquestions" set the anwer text like this
[Text of subquestion]|[text of left end]|[text of right end]
E.g.
|Banana|Apple
(you see, the [text of subquestion] is empty, only the left and right end texts)
To change the distance between the sliders there is an answer in:

Kind regards
