qgis - How to create a drop down list?

I want to show a drop down list in the feature attributes dialog.

Example:

I have 3 different building zones. The hot Wohnzon A, B residential zone and residential zone C. Now I have an attribute called the Zonenart. Now I track a new zone. And instead of the attribute "Zonenart" write something purely by hand, I want to be able to select it directly.

Thank you very much

Answer

Open the layer properties dialog and select the fields tab, click the button in the Edit Widgets column for the field and select Value Map

which will then give you this when using the info tool
