Hey @chefnewman!
For the text_input there currently isn’t a way to have it auto complete.
BUT if you’re looking to select a string from a column of strings in a DataFrame, where they can only use those specific strings, maybe select box or multi select will work for you? They allow you to populate a list of preselected options, and when you type into the field, they show options matching what you have typed so far. They also allow a dropdown box for people to look through all available options.
Here is when you start typing in the field:
Both of these widgets have this behaviour, the select box simply allows only one choice and multi select allows multiple selections!
Happy Streamlit-ing!
