    For more information see the expression widget for Mobile and Reactive Web Apps.


    Name Description Mandatory Default value Observations
    Name Identifies an element in the scope where it is defined, like a screen, action, or module. Yes
    Value Combination of values, operands, operators and variables or the result of a function whose value is computed at runtime. Yes
    Example Text to display in Preview and Design modes.
    Style Classes Specifies one or more style classes to apply to the widget. Separate multiple values with spaces.
    Escape Content Set as No to display directly the results of your expression in the screen content or set to Yes to perform escaping. Yes Yes Escaping an expression means that all accented and other special characters are replaced by a sequence that does not interfere with the protocols being used. In mobile apps expressions are escaped by default.
    Extended Properties
    Property Name of an attribute to add to the HTML translation for this element. You can pick a property from the drop-down list or type a free text. The name of the property will not be validated by the platform.

    Duplicated properties are not allowed. Spaces, " or ' are also not allowed.
    Value Value of the attribute. You can type the value directly or write expressions using the Expression Editor.

    If the Value is empty, the corresponding HTML tag is created as property="property". For example, the nowrap property does not require a value, therefore nowrap="nowrap" is added.
