In S60 MIDP 2.1, the POPUP type is usable only
in ChoiceGroup. When the element is selected in a POPUP ChoiceGroup,
the list is closed and the selected element is visible inline in the Form.
The size (small, medium, large) and style (STYLE_PLAIN, STYLE_BOLD, STYLE_ITALIC, STYLE_UNDERLINED, and combinations
of them) of Fonts can not be modified.
A ChoiceGroup element has only one line of text
regardless of the fit policy.
