import streamlit as st
from streamlit_sortables import sort_items

original_items = [
    {'header': 'first container',  'items': ['A', 'B', 'C', "C"]},
    {'header': 'second container', 'items': ['D', 'E', 'F']}
]

sorted_items = sort_items(original_items, multi_containers=True)

st.write(f'original_items: {original_items}')
st.write(f'sorted_items: {sorted_items}')
