hi Moynie, to create mega menu like demo site, you won’t need those option.
current option is the only option we use. and all other option will create confusion and we tend to remove. those plugin is a third party plugin, and we are creating alot of change on those plugin to make it fit with our themes.
option that removed is (style of this item, side of drop down element)
we going to remove another option that not going to be useful with the themes.
we are currently creating new documentation platform with better search function (search both documentation & forum). its still on development, and we will release it shortly.
