Chapter 3 Navigation Guidelines
To navigate Wireless Mark-up Language (WML) content, the user must move through and
between cards in one or more decks. The cards can contain many different types of
elements, including selection lists (items in a list), displayed information (such as an email
message), input fields, and multiple selection lists. To make applications run on multiple
browsers, follow a number of general rules.
Shared Feature Set: Navigation Guidelines
■ Do not assign more than one action of <do type="accept"> in any card.
■ Map the most commonly chosen action or most intuitive task to
<do type="accept">.
■ If there is to be more than one <do> task, ensure that the most common one is
defined first in the card.
■ Create an intuitive label for every <do> task.
This label will appear on the softkeys for the Openwave and Mitsubishi Trium
browsers and under the Options softkey for the Nokia browser. Note that when a label
is assigned to the
prev task, the Nokia 7110 browser displays a Back label on the
right. Always define a label of Back or Done for the
prev task for the Mitsubishi
Trium browser if the task is defined separately.
■ Capitalise only the first letter of labels of <do> elements except in words like OK.
Consistent style throughout all applications enhances usability.
■ Define a backward navigation action for each card.
Each card should have a <do type="prev">.
Example 3-1
<do type="prev" label="Back">
<prev/>
</do>
