This method specifies which preferred type of menu layout is to be used for a specific mobile device. The device properties delivered by SAP use the values linkList and selectionList, because there are two established variants for WAP-enabled devices:

• Numbered list of options This variant is mainly used on WAP-enabled devices with Openwave browser. The various menu options are implemented as <option> tags within a <select> tag. The Openwave browser displays this as a numbered list and a menu option can be selected by navigating or using the appropriate number key.
  
  
  It is strongly recommended to use this variant on Openwave browsers, because otherwise there is a significant difference in look-and-feel to other applications. However, on most of the other browsers this variant is not useful, because the <select> and <option> tags do not lead to a menu-like display.
• Link list. The various menu options are displayed as links below each other or next to each other. To select a menu option the user must navigate to the link and select it. As usual, these links are implemented by using the <a> or <anchor> tag. This variant is universal and can be used on all browsers, but for Openwave browsers you should use the first implementation variant due to the reasons mentioned above.
