Issue in using drop down

I have created an entity ‘names’ with an attribute ‘city_names’ which is an independent entity. In my homepage i am using a drop down placed in a data view attched to the entity ‘names’. I want the drop down to display the city names to the user so that he can select that city and the city name could be passed to the microflow as a parameter. But when I am selecting the attribute path in drop down it’s not showing the path. So if anyone could tell how to use drop down to get the city names from the entity which is not having any association as it’s not needed.

A dropdown will only show the object’s attributes that have type Enumeration or boolean. To get a list of citynames, you have to select an 1-* or *-* associated object. You will be able to select each attribute (of any type) of any associated object.
