Previously, I followed the instructions to use this section and added “section” and “custom liquid.” This is what it looked like before, achieving the expected result.
I could use the arrow to view different tab items. And the content showed perfectly.
This usually happens when the custom liquid code for the tabs is changed and loses its JS or has duplicates, so all tabs stack and show at once.
Compare your current custom liquid code to the original snippet you first used.
And check if any script tags and ids lines were accidentally deleted or
duplicated when editing.
If you can paste your current code, I can spot the issue. Have a nice day!
