The AutoComplete component in Ant Design does not have a direct property like autoAdjustOverflow found in the Dropdown component. However, you can control the dropdown placement using the placement property in AutoComplete.

If you want to prevent the dropdown from adjusting its position automatically, you might need to handle it with custom CSS or JavaScript logic to control the dropdown's behavior based on your specific requirements.

If this feature is crucial for your application, you might consider submitting a feature request to the Ant Design team for consideration in future updates.
