Combo template for selected option

I have an combo where i format the items given by the template property in the body config.
But i found no way (docs, …) how to format the value of the selected option being displayed in the combobox.
Example: Code Snippet

Good day @Mimu1988 ,

The template for the combobox itself can be added right to the suggest view (the combination of list and popup): Code Snippet

Yes thats what i wanted to achieve.
Thank you very much for your help Mariya.
