css ul li selection list

Please tell me about the selection and control of multi-layer lists in CSS.

The effect is just like the picture.

Let the first level menu be arranged horizontally, and the second, third and fourth level menus will be arranged vertically.

The font size and color of each level are different. I really can’t figure it out with CSS. I’m asking for help. I’m very anxious. Thank you.

You can analyze this kind of problem in the future
Your menu actually only has a total of 2 levels
Main menu: Horizontal
Font menu: Vertical

Main menu can be nested to contain submenus
Submenus can be nested to contain submenus
The following is a submenu The hierarchical problem is as long as the nested declaration of css is enough. How many nested declarations are there? There are only 2 levels
Main menu: Horizontal
