Additionally to the information of which country a participant is from, more detailed regional information
can be interesting too.
States as drop-down menu (in GERMAN)
With drop-down menus one can save a lot of space and kinda pretend to have a short
survey. However, one should still be careful applying drop-down menus and consider that a user needs more time to choose the appropriate answer in a drop-down menu than in choosing the right radio button or a check box. In some cases drop-down menus
are, on the other hand, the only choice, especially when the list of possible answers to choose from is rather
long. From cognitive psychology we know that the human being is able to comprehend up to six elements at the same time, hence drop-down menus should only be used with more than 7 possible
answers.
This is what it could look like:
In welchem
Kanton wohnen Sie?
States (Kantones Switzerland) with radio buttons
Simple list
List with "blind" table
In welchem
Kanton wohnen Sie?
States as checkboxes
The same applies here as it already has with radio buttons. The only
difference is that checkboxes allow multiple answers.
