When I create sub menu in menu component and add color : #77777 property in the icon category, menu doesn’t create color picker for the item and doesn’t change color.
What version are you using? I can’t reproduce on 8.0.6/8.0.7, so I’m pretty sure this is a fixed bug.
I use 8.0.3.
by the way it’s nice if we have style for color of icon.
