Hmm good point. I'm converting this to an enhancement because it's expected behavior today. We should probably think about adding a height parameter or a parameter to control line wrapping to st.multiselect. As a workaround, you can put it in a container with fixed height for now, which will enable scrolling:

st.container(height=50).multiselect(...)

Or you could try a popover container, so the multiselect doesn't show on the page itself:

st.popover("Show filter").multiselect(...)
