Layout Objects

Layouts helps you organize your objects including Panel components.

Panel provides layouts similar to the ones you know from Streamlit and many unique ones too.

Migration Steps

To migrate your layouts to Panel

• replace your Streamlit st.some_layout snake cased function with the corresponding Panel pn.SomeLayout CamelCased class.

You can identify the relevant layout to migrate to in the Layouts Section of the Component Gallery.

Columns Example

Streamlit Columns Example

import streamlit as st

col1, col2 = st.columns(2)

with col1:
    st.image("https://streamlit.io/images/brand/streamlit-logo-primary-colormark-darktext.png")
    st.write("# A faster way to build and share data apps")

with col2:
    st.image("https://panel.holoviz.org/_images/logo_horizontal_light_theme.png")
    st.write("# The powerful data exploration & web app framework for Python")

Panel Columns Example

You can access Panel’s layouts in the top-level pn namespace:

import panel as pn

pn.extension(sizing_mode="stretch_width", template="bootstrap")

row1 = pn.Row(
    pn.pane.Image(
        "https://streamlit.io/images/brand/streamlit-logo-primary-colormark-darktext.png",
        align="center",
    ),
    pn.pane.Image(
        "https://panel.holoviz.org/_images/logo_horizontal_light_theme.png",
        align="center",
    ),
)
row2 = pn.Row(
    "# A faster way to build and share data apps",
    "# The powerful data exploration & web app framework for Python",
)

pn.Column(row1, row2).servable()

Panels Column and Row are list like objects. So you can use familiar methods like .append, .pop and [] indexing when you work with them. For the details check out the Column Guide and the Row Guide
