Streamlit 1.37 Release | New Features Explained

[@amanahmed6057]

is thery any feature of streamlit in which if we select multiselect , more than 2 and drop down height increases every time , I know that we can make the drop down scrollablle but is there any way to use in expander , because when we use expander , it will shift all the graph to down , Its okay when you have 4 options but when you have 20 options in expander than it would shifted all the graph upto down ,which is very irritating.

When using st.multiselect(), the drop-down menu only shows around 7 options before having to scroll to see the other options.
For example :
# options
options = ['Option ' + str(i+1) for i in np.arange(0,20,1)]
# using multiselect
st.multiselect('test', options)
But you can tackle this issue by using st.expander(), looping on multiple st.checkbox() and using the st.session_state() to gather all selected options. This way, when you open the expander, all options will be displayed at once.
# using expander + checkbox
with st.expander('Choose an option'):
for i in options:
st.checkbox(i, key=i)
selected_options = [key for key, value in st.session_state.items() if value is True]
st.write(selected_options)
Try this and let me know if it works
