I’m trying to add columns to the expander, but unfortunately it doesn’t seem to take effect

Steps to reproduce

Code snippet:

            expanderList.append(st.expander('💡 Generate Results %s'%lineNum, expanded=False))
            MODEL_CONFIG['rank_list_len']=4
            columns = expanderList[lineNum].columns([1] * MODEL_CONFIG['rank_list_len'])
            for i, c in enumerate(columns):
                with c:
                    choice = expanderList[lineNum].selectbox(f'i+1', rank_choices,key=tagNum,
                      index=index)
                    if choice != -1 and choice in rank_results:
                    else:
                        rank_results[i] = choice
               
                    texts[i] = expanderList[lineNum].text_area('answer%s:'%tagNum,texts[i],height=200)
                    
                tagNum = tagNum + 1
                index = index + 1

Expected behavior:Add several columns to the expander

Actual behavior:Unable to recognize column, still changed layout to row

Without carefully parsing your code to see if there is something else going on, the thing that jumps out at me is:

You are trying to write in a column while simultaneously specifying you are not writing in the column. If you want to use with c: then inside should be st.selectbox. Not <some other location not c>.selectbox.

Thank you very much for solving my problem. I thought I needed to add controls like this, but I was wrong
