Aligning Expanders in Streamlit Columns

I have an app that uses a pane with multiple information on it like in the screenshot attached. I have used the streamlit.columns functionality to divide the space in different columns and I have managed to properly align the text fields with the plots using css and html.

My problem is that I would like to align the expanders also alongside all the other components so that my app looks organised. Can you please indicate how to align the expanders ?
