Scroll 2 elements at once

Has anybody used Javascript to scroll 2 elements at once? Here’s the use case:

  • There are 4 repeating groups.
  • RG1 is a vertical list of student names.
  • To the right of RG1 is RG2. RG2 is a horizontal list of categories.
  • Above RG2 is a horizontal list of categories, RG3, used as a header that doesn’t move so it’s always visible on page.
  • Inside RG 2 is a vertical list of student ratings, RG4. This shows the student rating per category.

I want to be able to do this:

  • When RG1 is scrolled up and down, also scroll RG3.
  • When RG3 is scrolled up and down, also scroll RG1.
  • When RG4 is scrolled left and right, also scroll RG2.
  • When RG2 is scrolled left and right, also scroll RG4.

I’ve found an approach HERE, but am curious if anybody has done this in Bubble without using code.

I really wanna know the solution :sob:

I guess this approach is close to what i expected, but i couldn’t scroll at the same time on bubble. Writing javascript is not easy for me.
