So, my question is what other implicit elements are there? I want to have a white menu arrow and I can't work out what its called. 回答1: They are called "anonymous nodes" and you can see them in DOM Inspector for example.

问题 I have an accordion menu that works nicely. But now, I want only one parent item expanded at a time. In other words, when I click to expand one parent item, any other expanded parent item needs to collapse.
