if you dont like the separator's color, change line 435's color code
renderContext.drawColoredRect(1, 13, dropdownWidth - 1, 14, 0xffd0d0d0);

hello, thank you for this PR, i preferred looking at the other one, because i am still unsure about some aspects of key input (such as IMEs, for example). in a perfect world i would first hash out text inputs that just portal a vanilla component with all the niceties of that (IME, better copying and clicking) and then add things like search bars and such. if you want to PR this still (and the scrolling alone isnt enough for your usecase) then i can look into rebasing this, but for now i think scrolling should be enough.

No problem it's just 2 approaches to fix the issue, the scroll is good enough so no issue in closing it
