The autocomplete feature helps your chatbot provide a list of up to 5 items that are contextualized to what the user is currently typing. Think of it as quickly hitting one of the first Google search results!
Autocomplete can be configured in your webapp's settings panel. It can also be disabled/reenabled programmatically in your CSML script with the following syntax:
say Autocomplete(false) // disable autocomplete say Autocomplete(true) // enabled autocomplete
To configure Autocomplete, you need to have a backend endpoint that will handle the requests and respond accordingly. Read more in the CSML Studio docs!
