Add the Control to a Screen

1. Create a Form Screen or edit a Form Screen in which to add the control.

2. Expand the Advanced category to the left of the Screen Builder canvas, and then locate the Captcha icon .
3. Drag the Captcha icon into the Screen Builder canvas. Existing controls on the Screen Builder canvas adjust positioning based on where you drag the control.

Settings

The Captcha control has the following panels that contain settings:

• Variable panel

• Configuration panel

• Advanced panel

Variable Panel Settings

Click the control while in Design mode, and then click the Variable panel that is on the right side of the Screen Builder canvas.

Below are the settings for the Captcha control in the Variable panel:

• Variable Name

• Required

Variable Name

Edit the default Variable Name setting value for this control if necessary. The Variable Name setting value represents data in this control during Requests. Ensure that the Variable Name setting value is a unique name from other controls in this Screen and contains at least one letter. This is a required setting.

Use the Variable Name setting value in the following ways:

• Reference this control by its Variable Name setting's value. The Data Preview panel in Preview mode represents the state of the Captcha control using its Variable Name value in the Request's JSON data model.

• Reference this control's value in a different Screen Builder control. To do so, use mustache syntax and reference this control's Variable Name value in the target control. Example: {{ Captcha }}.

• Reference this value in Visibility Rule setting expressions.

See best practices when editing a Request variable name.

Required

Select to indicate that this control is required. This option is selected by default.

Configuration Panel Settings

Click the control while in Design mode, and then click the Configuration panel that is on the right side of the Screen Builder canvas. Below is a setting for the Captcha control in the Configuration panel.

Google reCaptcha Sitekey

In the Google reCaptcha Sitekey setting, enter the Google site key. For more information on how to get a site key, see Register a new site.

Advanced Panel Settings

Click the control while in Design mode, and then click the Advanced panel that is on the right side of the Screen Builder canvas.

Below are the settings for the Image control in the Advanced panel:

• Visibility Rule

• Device Visibility

• CSS Selector Name

Visibility Rule

Specify an expression that indicates the condition(s) under which this control displays. See Expression Syntax Components. If this setting does not have an expression, then this control displays by default.

Note the following regarding how to use visibility rules:

• To make this control hidden until another control contains a value, enter the Variable Name setting value of that control to this control's Visibility Rule setting.

• Visibility rules override custom CSS settings.

See the following best practices regarding custom CSS in Screens:

• Editing a CSS name to represent this control in custom CSS syntax

• Visibility rules override custom CSS settings

Device Visibility

Select on which device types this control displays:

• Desktop: The control displays only on desktop devices. Enable the Show for Desktop toggle key.

• Mobile: The control displays only on mobile devices. Enable the Show for Mobile toggle key.

• Both: The control displays on both desktop and mobile devices. Both toggle keys are enabled by default.

CSS Selector Name

Enter the value to represent this control in custom CSS syntax when in Custom CSS mode. As a best practice, use the same CSS Selector Name value on different controls of the same type to apply the same custom CSS style to all those controls.

Move the Control on the Page

See Move a Control on the Page.

Follow these steps to delete a control from a Screen page:

1. Select the control to be deleted.

2. Click the Delete button. The control deletes. Other controls on that Screen page adjust their locations automatically.
