.parent() inside multiple selector

Question

I want to select a couple of targets:

1. Every direct li descendant whose parent is not .sub-menu (unless it's the last, cf. 2.)
2. Every last li element of an ul.sub-menu
3. Exclude all li's that are parent to a ul.sub-menu

I was thinking something like this, but that doesn't seem to work: $("ul:not(.sub-menu) > li, ul.sub-menu > li:last, ('ul.sub-menu').parent()")

How would one go about when trying to select an element with non-css selectors inside multiple selectors?

Answer 1

$('ul:not(.sub-menu) > li, ul.sub-menu > li:last-child').not(':has(ul.sub-menu)');

Answer 2

Try this one:

$('ul:not(.sub-menu) > li, ul.sub-menu > li:last-child, li:not(:has(ul.sub-menu))')
