Auto Suggestion Input Type Field

how to create Auto Suggestion Input Type ? I can use select option with use tag in “Render type” option.
But there is no option to add new value in List from object form if required value is not in list.

You have to write it manually - see https://pimcore.com/docs/6.x/Development_Documentation/Extending_Pimcore/Bundle_Developers_Guide/Adding_Object_Datatypes.html for more details.
