List Items Vertically Spaced Evenly Within a Flexbox Container

Alright guys, I’m learning CSS right now, and I’m kind of stumped as to why I can’t get it to do what I want it to do. It’s probably something extremely simple that I’m overlooking.

I’m wanting to have an unordered list containing sub-lists vertically spaced evenly within a flexbox sidebar container and the sub-list items doing the same between each list item. Everything I’ve tried so far hasn’t had any effect on how the list items are displayed.

Any help is appreciated.

Do you think that some aspect of phpList is responsible for your layout not rendering correctly? Have you tested it independently of phpList, on a static website or sandbox like
