  • Examples showing recommended widgets for 2-5 options vs many options, and migration from old patterns to modern ones.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I choose the right Streamlit selection widget for my options?▼

For 2-5 options, use segmented_control or pills to keep all choices visible. For many options, use selectbox or multiselect to hide choices behind a dropdown and reduce interface clutter.

What is the difference between Streamlit pills and segmented_control?▼

Both Streamlit pills and segmented_control display small option sets visibly, but segmented_control emphasizes a mutually exclusive toggle layout, while pills offer a compact button-like selection format for few choices.

When should I use Streamlit multiselect instead of selectbox?▼

Use Streamlit multiselect when users need to pick multiple items from a large list simultaneously. Use selectbox when users should only choose a single option from a dropdown to ensure predictable selection behavior.

How do I migrate from Streamlit selectbox to modern widgets for small option sets?▼

Migrate from Streamlit selectbox to modern widgets by replacing dropdowns containing 2-5 options with segmented_control or pills, improving accessibility and UI predictability by making all options immediately visible.

Are there limitations to using Streamlit segmented_control for many options?▼

Streamlit segmented_control is limited to small option sets of 2-5 items. Using it for many options causes layout overflow and poor accessibility, requiring selectbox or multiselect dropdowns instead.
