Within the Joomla (4) template JA Campaign I use the Megamenu option (Build Megamenu enabled), under Global Settings, Addons I also enabled font.iconnoon, font.awesome4, and font.awesome5 and under the option "Navigation" filled in the "Item icon" option. Whatever I enter there, I don't see any icon appearing for the different options (words) of my main menu. Am I forgetting to set or enable something? Who can help me?
