Thanks for sharing this Emma, a few notes from my side I hope you'll find useful.
Setting max-height and opacity makes the options not visible, but this doesn't mean they are not available to ATs or KB users. Try using the tab key (or a screen-reader) and you will see that those no-longer-visible options can still receive focus and are actually there.
You can fix this using display: none or setting aria-hidden: true.
I always test my work using a screen-reader (voiceover) and pretty much all the times I am amazed by the amount of extra work I need to do to make it more user-friendly.
Good to see people taking accessibility seriously!
Keep up with the good work
