Dependent fields and sections
- Both fields and sections can:
- Be shown or hidden depending on the value of other fields, by setting their visibility property.
- Become read-only, as opposed to read-write, depending on the value of other fields, by setting their read-only property.
- In addition, fields can also:
- Have a dynamic value set when the form is first loaded by users, by setting their initial value property.
- Have a value that is updated "live" as users set or change the value of other fields in the form, by setting their calculated value property.
By using a combination of the aforementioned visibility, read-only, initial value, and calculated value properties for sections and fields, you can create forms that are very dynamic, which can behave like a spreadsheet, or like a small application.
Say you want to show a textarea when users check a checkbox to indicate they want to provide more details:
Textarea shown if checkbox is checked
- 1.Add a Single Checkbox control, open its Control Settings, name it
- 2.Add a Plain Text Area control, open its Control Settings, open the Formulas tab, set the Visibility to Formula, an enter
$provide-additional-details/string() = 'true'.
