Thank you Keegan. An interesting idea as had posted a help topic as had used css prior to accomplish this.
One member @nolo had given me a great piece of css as I was using this to hide many subcategories so only Parents show in hamburger.
So as a Though maybe adding a toggle to hide just subcategories.
.hamburger-panel .category-link.subcategory {
display:none;
}This setting can make things very convenient if ppl have alot of subs to hide.
