css - html - controlling how many options show in a select element -

-

so have drop down (select) element. problem if there long list in it, "drops" upwards instead of downwards.

is there way should scroll rather show of them @ once?

i know there's "size" that's how many visible @ once (i want 1 visible, normal)

or reason it's not having scrollbar automatically caused it's containing div? need know should end or something?

the way works browser. nothing can it, other building own drop-down js.
