Default Value
Enter the default value this control displays. The default value can be assigned as a Request variable, text or JavaScript. When the Screen submits, the Request uses this control's default value unless the Request participant changes it. When using a Request variable in the Default Value setting, consider the following:
If the Request variable is empty, the control does not display any value by default.
When the Request variable is assigned a value for the first time, this value becomes the permanent default value of the control.
Any further changes to the Request variable do not affect the default value of the control.
The Default Value setting supports using Request variables in mustache syntax. For example, if the Default Value setting is {{ FirstName }} {{ LastName }}
from which a Request participant entered her first name and last name in separate controls (respectively) earlier in that Request, this control displays the contents of those controls by default during the Request.
There are two ways to enter the default value this control displays.
Visibility Rule
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.
Device Visibility

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.

Assistive technology, such as screen readers, read the Aria Label setting value.
This control has a visual indication of its purpose, such as a button that uses a graphic instead of text, but still needs to clarify that purpose for anyone who cannot access the visual indication.
Tab Order
Tab order determines the sequential navigation order to navigate a Screen's controls using a keyboard interface. Assistive technology users often use a keyboard for navigation.
