As you build dashboards with Streamlit, organizing your content is essential for creating clear, user-friendly interfaces. Streamlit provides several layout primitives that help you arrange components effectively: st.columns, st.container, and st.expander. Each serves a unique purpose. st.columns allows you to place content side by side, perfect for comparing visualizations or grouping related controls. st.container lets you group elements together, maintaining their relative positioning and helping you manage complex layouts. st.expander provides collapsible sections, which are useful for hiding details or advanced options until the user needs them. Using these primitives, you can design dashboards that are both visually appealing and easy to navigate.

Arranging components with columns, as demonstrated above, brings clarity to your dashboard by grouping related content together in a logical, easy-to-read format. Placing a chart and its description side by side helps users understand the data more quickly, reducing the need to scroll or search for context. This structure improves usability, making your dashboard more intuitive and visually organized. By leveraging layout primitives like st.columns, you ensure that your dashboard remains clean and effective as it grows in complexity.
