Selection is displayed as combobox. And it is not possible to choow way of displaying.
option do not allow to enter anything except name in admininstration page.
I found that it is possible to choose way of displaying in Enum class. But this type is deprecated. Also i do not find way to display both: name and value of option.
Another example, I need to meke folloving:
choose your zodiac:
Option name: Cancer Option value: images/zodiac-cancer.gif
Problem, that i can get only word "Cancer", but no way to get name of image. With english it's no problem, but in lithuanian zodiac names has utf-8 symbols, which i cannot use for filenames.
