Their disadvantage compared to related controls like radio buttons or lists is that the options are not visible without further interaction. * Use combo boxes instead of radio buttons for more than four mutually exclusive options. * Don't use them for less than three options or more than 10 choices. In the latter case, use lists instead. * In general, controls that show the options without further user interaction are preferable, except for the following cases: ** the list of options may change over time, ** the contents are obvious from the label and the one selected item, for example ''Month'' and ''January'' ** the combo box is part of a related sequence of controls. For example, to set a reminder to ring 5 hours or minutes before or after an event. * Provide a descriptive label to the left (in left-to-right scripts), in some cases above the combo box. Don't forget to create a buddy relation so access keys are assigned. * Don't initiate an action when the user selects an item from a drop-down list. * Make sure the items are easily accessible via keyboard by moving distinctive letters to the beginning of each option. For example, in a list of countries on continents, write ''Germany (Europe)'' instead of ''Europe/Germany''. * Use sentence style capitalization for the label and the options. * If activating a choice affects the appearance or the enabled state of other controls, place them next to the radio button or in the next row (indented).
