Selecting two or more multiselect to sort it out

hello all,

Not only I am a newbie in python and all but I am more of an historian.

I am working on some combat results and i would like to sort my data with two or more sidebar widgets.

inputselect = {
    "theater": st.sidebar.multiselect(
        'Select Theater of operation', data['theater'].unique()
    "Airforce": st.sidebar.multiselect(
        'Select Airforce', data['country_flying_mission'].unique()



Now, I understand I need to have inputselect used as a parameter in my st.write(data[“inputselect”]) but i have no idea how to do pass the arguments.

Is there an easier way to filter data via the sidebar?
