A compare tool like this would be possible with Wix Code?
Will really appreciate it if any WIX team member kindly help clarify it.
Comparing Products is already done with the use of elements like the Repeaters
Changing the displayed items dynamically could be done by Dropdown onChange() event and changing the repeater data accordingly.
Thank you very much for your information. Very helpful and clarified my concern.
