Accordian Menu for Categories

-- url of the page with the problem -- : new.stonecreekltd.com
-- HikaShop version -- : 4.71
-- Joomla version -- : 4.21
-- PHP version -- : 8.1
-- Browser(s) name and version -- : Edge
-- Error-message(debug-mod must be tuned on) -- : Category 2 levels doesn't collapse.

I'd like to recreate the demo of the categories module, but can't see the settings within the demo module plus it is in the OLD version of Joomla. I can't find documentation to show an accordian style categories list.
