Make st.selectbox dropdown re-open at position of last selected option, not at the top every time

[cmayoracurzio]

Problem

When using a st.selectbox widget with many options, the dropdown always reopens at the top, even if the last selected option is somewhere down in the list of options. This is only noticeable when the dropdown has a scrollbar (i.e., when there are many options).

Related yet different issue: #4671

Solution

Preferred solution: The dropdown in st.selectbox always opens up at position of last selected option.

Additional context

From the user's perspective, reopening a st.selectbox dropdown at a position that doesn't show the last selected option is confusing.

Hey @marduk2,

thanks for the idea! This seems reasonable, I'll add it to our roadmap. It's not super high priority in my eyes though, so I'd expect this to take a bit longer to fix.

Hey there @jrieke,

Thanks for replying and tagging this properly, appreciate it! Our users will be very happy if this improvement gets made :)

Also consider the other yet related issue which I already added a couple of months ago: #4671 (mentioning it in case it makes sense to tackle both at the same time when you get to them).

+1 here. Especially with long dropdowns, not having to scroll is very much desired by our users as well.
