Only vaguely. I think JS is needed to make such a menu "tabbable".
At the bottom of this page they list a lot of things we *should* do. Alas they don't tell us *how* we should do them.
https://accessuse.eu/en/drop-down-menus.html
Here they talk about an accessible super duper menu Adobe of all people has made available to the public.

Here's WAI's take on it.

This seems to work in Firefox and Chromium. MSIE and Edge running on EdgeHTML don't support it, but I suppose Edge will add support once it becomes Chromium-based:
CSS
CODE
li ul {display: none;}
li:focus-within ul,
li:hover ul {display: block;}
HTML
CODE
<ul>
<li><a href="#">top 1</a></li>
<li><a href="#">top 2</a>
<ul>
<li><a href="#">sub 1</a></li>
<li><a href="#">sub 2</a></li>
</ul>
</li>
<li><a href="#">top 3</a></li>
</ul>
