Automatically insert single suggestions
Choose whether you want to automatically complete your code if there's just one code completion suggestion for basic and/or smart completion.

Machine Leaning-assisted Completion
Select if you want to utilize machine learning models to rank most suitable items higher in the suggestions list.
Insert default argument values in completions
By default, when you select and apply a completion suggestion, IntelliJ IDEA inserts default argument values so you only need to fill in the field in the inserted template.
Clear the checkbox to suppress such behavior and fill in the arguments yourself.
Only type-based completion
By default, IntelliJ IDEA suggests completion for symbols regardless of their types. With this approach, in complicated cases the list shows multiple completion variants.

Suggest items with optional chaining for nullable types
By default, IntelliJ IDEA suggests completion for symbols with the optional chaining operator (?). To suppress showing such suggestions, clear the checkbox.
Expand method bodies in completion for overrides
By default, when you want to override a method from the parent class or interface and select this method from the list of completion suggestions, IntelliJ IDEA automatically adds parameters, generates a
