If your option dropdown is showing a very long list of items and / or doesn’t show all items – here is how you can fix it.
The fix is by setting the "form_select-list” layer to have a max-height AND setting to scroll automatically if it hits that max-height.
Max-height: 300px
(or to your preference)
Overflow: Auto
(this adds scroll if it goes over)
Be sure that Display:None is set so that it will not appear by default when the page is loaded.

This will now make the super long dropdown list into a scrollable box that is easier to navigate for customers.
