After you create a control, you configure how the control is displayed. You can specify whether the control is editable at run time, the width of the control, the label format for the control, and one or more CSS helper classes to adjust the control's appearance and placement.

1. On the Presentation tab of the Properties panel, specify the Edit options for the control. These selections take precedence over section and harness settings:

   • Auto – The control is editable for an application user, depending on the edit mode of the enclosing section or harness.
   • Read-only (always) – The property values are read-only for the user and you cannot change the size of the control.
   • Read-only (expression) – Select this setting and in the adjacent field press the Down Arrow key to select the expression used to evaluate the conditions in which the property values are read-only.
   • Read-only (when rule) – Select this setting and in the adjacent field press the Down Arrow key to select the when rule that determines the conditions in which the list's property values are read-only.
   • Editable – The list is editable for an application end user.

2. Set the Specify size option:

   • Auto – Select this setting to have the layout determine the width of the control.
   • Custom – Select this setting to specify a fixed width for the list in the corresponding Width field. You can set the list's width in pixels or as a percentage.

3. Use the Label format field to set the format of the control's label.

4. To adjust the control's appearance and behavior, use the fields under Advanced Presentation Options.

   Instead of creating a new custom format in the skin, you can adjust elements in a cell by applying Cascading Style Sheet (CSS) helper classes. For example, you can use a CSS helper class to center an element in a cell or to double the standard right margin for the element.

   • Cell read-write classes – Click the Open helper class picker icon to specify one or more CSS helper classes to apply to this cell when the form is displayed in read-write mode. You can enter several helper classes, separated by a space. Alternatively, you can enter the name of a custom style to apply to this cell.
   • Cell read-only classes – Click the Open helper class picker icon to specify one or more CSS helper classes to apply to this cell when the form is displayed in read-only mode. You can enter several helper classes, separated by a space. Alternatively, you can enter the name of a custom style to apply to this cell.
   • Inline style (not for production use) – You can use this field to define an inline style by entering CSS code. However, entering an inline style results in a guardrail warning. For maintainability and reuse, the recommended approach is to use read-write or read-only classes.
