Smart layout Properties - General tab

Select one of the following to control visibility:

• Always : always visible
• Condition (expression) : the region is visible under the specified condition. In the field that displays, select a condition or click the Gear icon to open the Condition Builder. You can define a simple expression based on the comparison of a pair of constants, properties, or both, combined by Boolean operators, such as .Color="Red". You can combine the expression with a when condition rule or another expression using the && and || operators.
• Condition (when) : the region is visible under the specified condition. In the field that displays, select a when rule. Click the Open icon to create a new when condition or review an existing when condition.

As a best practice, use the Condition Builder to edit this field. Click the Open condition builder icon to open the tool. See Using the Condition Builder to configure dynamic UI actions.

If this section is to become part of navigation in a composite portal, you can make the header visible only when a specific space is the current space. Enter an expression here similar to the following:

pyCurrentSpace=="ASpaceName"

Row restrictions remain in force, but you can remove them if all columns have a None type. If all restrictions are removed, you can change the height of individual rows, or the width of individual columns. With this flexibility, you can support a wider variety of scenarios. However, columns will not automatically adjust when switching between Single, Double, and Triple layouts.

If you Allow Changes to Columns , you cannot undo this change.

See PDN article Using SmartLayout features — How to customize, use Merging Cells, and change Field Width.

• Pixels (Fit Content) — To have the column widths on the user form or flow action form match, in pixels, the column widths on the current rule form. (Internet Explorer may adjust column widths to avoid truncating values in the column.)
• Pixels (Fixed) — To specify a column width exactly. The browser uses this width even when data values may be longer (after applying styles, margins, padding, and so on). The display may truncate a data value if the value is wider than width defined by the pixel value.
• Fill (100% ) — To have the column widths on the user flow action form adjust to fractions of the total width of the user form or flow action form. For example, if you adjust the column on the rule form to be 25 percent of the total width, the column on the user form or flow action form will be 25 percent of the form width, and will grow or shrink if a user resizes the form.
• Stretch-Spacer — To expand or contract the spacer widths so that the layout fits the entire form. The Field and Label column widths do not change. You cannot use this setting if the Smart Layout value is Single.

If you choose px-fixed and a property value at runtime is wider than width defined by the pixel value, the value is truncated, and users are unable to see the full value.

If you plan to localize the application, choose the text carefully and limit the length to no more than 64 characters. A field value rule with this text as the final key part is needed for each locale. See About the Localization wizard.

Appears when you select Conditional Visibility and enter a simple expression in the field that displays.

Select the Run visibility condition on client check box to cause dynamic execution of the condition each time the value of a property stated in the condition changes.

Conditions are automatically re-evaluated when the user updates a property value. By default, controls that allow typing, such as Text Input, are evaluated when the user leaves the field. To re-evaluate conditions as the user types, use the Apply Conditions action with a Keyboard event. See Control Form — Completing the Control tab.

Select to delay loading the section content at runtime until the user clicks the header. Deferring enables users to start using other parts of the page rather than waiting for this section to load.

To enable users to take actions, such as submit, on a work item while other content is still being loaded, configure sections to use defer loaded asynchronous declare pages. See PDN How to configure non-blocking UI using Asynchronous Declare Pages (ADP).
