Layouts and Containers

Complex layouts

Streamlit provides several options for controlling how different elements are laid out on the screen.

Display items in a sidebar.

st.sidebar.write("This lives in the sidebar")
st.sidebar.button("Click me!")

Insert containers laid out as side-by-side columns.

col1, col2 = st.columns(2)
col1.write("this is column 1")
col2.write("this is column 2")

Insert containers separated into tabs.

tab1, tab2 = st.tabs(["Tab 1", "Tab2"])
tab1.write("this is tab 1")
tab2.write("this is tab 2")

Insert a multi-element container that can be expanded/collapsed.

with st.expander("Open to see more"):
  st.write("This is more content")

Insert a multi-element container.

c = st.container()
st.write("This will show last")
c.write("This will show first")
c.write("This will show second")

Insert a single-element container.

c = st.empty()
st.write("This will show last")
c.write("This will be replaced")
c.write("This will show first")
