Hi,

create a list of select items that you will set in <f:selectItems> tag:

    List<SelectItem> selectOptions = new ArrayList<SelectItem>();

    selectOptions.add(new SelectItem(someValue1, "some label 1"));

    selectOptions.add(new SelectItem(someValue2, "some label 2"));

    ....

Regards,

Palo

B.t.w. if do not want to convert your list of custom objects to list of SelectItem's - just use var, itemValue and itemLabel attributes of f:selectItems.

You can use map
