Side menu hide all subcategories by default
I've read several similar posts, but have not seen any successful solutions posted. I'm wanting the subcategories to collapse (hide) by default when the page loads and the subcategories shall expand (display) only when the clicked.
Currently, all categories are expanded displaying all sub categories (and there are ALOT) which forces the user to scroll extensively to find what they need.
Can you point me in the right direction for updating the appropriate file, and line of code?
Thank you.
