[Python] Streamlit multiselect, if I don't select anything, doesn't show data frame

I am building a Streamlit app. Part of my code includes multiselect as follows, when I dont select anything in multiselect, I want to show whole data frame without any filtration, but it doesn't show any data, how should I modify the code?

type_ = df_temp.TYPE.unique().tolist()

options, options2 = st.columns([0.1, 0.1])

options2 = options2.multiselect('Select Type', type_ )
