Need help with layout - columns within columns?

Hi there :wave:, I need to have a c1 that is like a vertical banner on the left of the screen, c2 - c4 to the right of the screen:

c1, c2, c3, c4 = st.beta_columns(4)

In c2 - c4, a st.title() starting at c2, 3 multiselect (one multiselect per column) and a dataframe starting at c2.

I tried different combinations of columns and containers and nothing comes up right. So, basically:

c1    c2    c3    c4
        3 multiselect

st.title somehow screws up the alignment too… does anyone know how to code this out correctly? Thank you!
