public class MLComboBox extends MLItem
ComboBox is a value field that will show a overlay widget to select its value from.

The combo-box value can be preceded with a leading text with an optional fixed width, and the text entry will take up the remaining space in the list item.

The combo-box may have a fixed width and be trailing justified (i.e. right for LTR or left for RTL).

An optional description text can be added to the bottom of the list item.
