Dropdown script component

Value binds a component to the variable selected. For example, if you bind a text input component to a variable, the input box will always display the value of that variable, ignoring any placeholder text specified. The variable is automatically updated with text typed by the user, subject to validation processing.

Other controls, radio buttons for example, use Value with a Selected Value Text setting. When the radio button is selected at runtime, its "Selected Value Text" becomes the new value of the variable. This way, each radio button can assign a different value to same variable.

When a calendar control is bound to the variable, its value is set to the date selected by the control. Since variables can preset the value of visual controls and also be set by them, binding is a powerful and often-used technique.

Placeholder text displays a hint to the user.

For a text input, placeholder text is shown until the user types input. If the user clears the contents of an input box, then placeholder text is re-displayed.

For a dropdown, placeholder text prompts the user to make a selection.

The placeholder is replaced after the user selects an item.

Configure the Label by selecting a variable, entering text, and choosing a position.

This property applies to dropdown components only. It adds or removes list items from a dropdown.

1. By default, a dropdown has no items. To add choices for users to select from, expand the Advanced property group.
   
2. Click Edit List under Options.
3. Click Add New Item.
4. For each item, configure text to display and a return value:
   
   1. Set Value to a unique string or number. When the item is chosen, value indicates which item the user selected. Value can optionally be assigned by a variable.
   2. Set Display to text a user can choose in the drop list. Display text can optionally be assigned by a variable.
5. Click Add to save the item.
6. The Editing List window summarizes items added. You can reorder items by clicking up/down arrows, delete items by clicking the trash icon, or add additional list items to the dropdown.
7. Click Add New Item to add additional items.
8. When finished, click Close.

Determines whether the user is required to type or select a value. The default is False, which means that user interaction is optional.

The user interface visually indicates whether user input is optional. 

Optional input is indicated by a label below the component:

Configures width to a fixed size, to grow as needed to display content, or to consume as much space as possible relative to other components, using weighting to influence size adjustments.

Setting	Description
	Auto-sizing configures the component to shrink or grow in accordance with its contents. For example, the width of a label can grow depending up on how much text it contains.
	Stretch allows a component to consume as much space as possible relative to other components, using weighting to influence size adjustments. If two components are both set to stretch, they are both allocated 50% of the remaining space by default. This proportion can be adjusted by changing the weight value. For example, if you set one component to a weight of 200, and the other to a weight of 100, then the first component occupies two thirds of the remaining space, while the other only takes one third. The first component appears twice the size of the other component, since its weight was two times the second component's weight.
	Sets a fixed size in pixels. You can type an integer value into the box, or use up or down arrows to increment or decrement size. These arrows are visible when the component has focus.

Aligns a component to the left, right, or center, relative to its parent container.

Setting	Example

Margins set left, right, top, and bottom spacing around a border.

1. To optionally update all margin values at once, press the Set All button for Margin in the properties panel.

   

2. Click the value field for a margin. A spin control appears in that field.

3. Use the spin control to increase or decrease the margin. If Set All was selected, the change is applied to all margins.

   

   The component is immediately repositioned using its new margin setting.

Sets the visibility of a component based on the value of a Boolean (True or False) variable, or an expression.

To set the Visible property based on a variable:

1. Click the Layout property group.
2. Under Visible, click Select Variable.
3. Select a variable, or optionally create a new Yes/No variable and then assign that new variable to the Visible property.
4. At runtime, the component is visible when the value of the variable is True. Conversely it is hidden when the variable's value is False.

To set the Visible property based on an expression:

1. Click the Layout property group.
2. Under Visible, select True/False Expression.
3. In the Insert Variable box, enter an expression .

At runtime, the component is visible when the expression is True. The component is hidden when the expression is False.

Configure the Label Style by selecting:

• Font
• Style
• Size
• Justification

Optional input is indicated by a label below the component:

All components are enabled by default. The Disabled property binds a True/False variable to a component, to disable or enable it based on the runtime value of the variable.

1. 1. To create a True/False variable, click the Variables tab.

   2. Click Add  to add a variable.

      

   3. Select True/False as the data type.

      

   4. In the Name box, type a descriptive name.

      

   5. Set Default Value to True or False.

      • If the variable is True, then the component is disabled.

      • If the variable is False, then the component is enabled.

   6. To save the variable, click Apply.

   7. Assign the variable to the Disabled property. Below Disabled, click Select Variable.

      

   8. Select the True/False variable.

      

The Change Action property allows you to set an action that executes when the state or value of this component is changed.

You can select a Scripter action, an Outbound Action, or a custom action. Outbound actions are not available unless the Outbound property is enabled.
