A method of displaying data on a display screen is provided wherein first and second display zones are provided on the display screen. The display zones are sized so that, in combination, they substantially occupy a predetermined display area of the display screen which may, for example, be the display screen of a handheld device. In one embodiment, the relative sizes of the display zones are dynamically set dependent upon content to be displayed in each display zone. For example, a display zone for displaying list content may be larger than a display zone for displaying form content. The display zones may be arranged in a lateral fashion wherein they have substantially similar heights, or arranged in a stacked fashion with substantially similar widths. The respective widths or heights, as the case may be, may be sized dependent upon the content for display in each zone.
