Problem

st.selectbox is one of the most widely used Streamlit widgets, as it allows the user to select one option from a list of options.

The current implementation allows text searching, which for some use cases makes sense (e.g., a long list of countries), but for others it makes the widget feel buggy (e.g., a selectbox with very few options, such as "Yes, No").

Solution

MVP: An example on how to use the CSS st.markdown trick to disable text search in st.selectbox.

Preferred solution: A parameter that allows enabling/disabling the text search behavior in st.selectbox.
