Sub Form

Sub Form can be used to create forms within your main form. A SubForm can help you break longer forms into shorter ones.

To add ‘SubForm’ feature in your form, just drag the Sub Form widget from the left panel to the digital mobile screen in the middle.

For example, your inspection form can have subforms such as ‘Premise A,’ ‘Premise B,’ etc.

Properties of a Sub Form

1. Label

You can change the name of the ‘SubForm’ using a label property. It is ‘‘SubForm’ by default.

On the right panel, go to the label section and you can type the required text that you want. The same name will appear on the form.

For example, you can keep the label of your SubForm as ‘Premise A.’

2. Unique Identifier

Every field will have a unique identifier. No two unique identifiers for fields will be the same.

Please note that ‘Unique Identifier’ property is just for reference purpose only. The user need not have to do anything to this property, it can be referred when there are fields created with the same names.

When you create two fields with the same names, it might get confusing when you are setting a condition and you wouldn’t know which field is which.

For example,

If you have created a field ‘address’ - and set a visibility condition to it saying the ‘address’ field will be only visible if you have entered the ‘Phone number.’

But if there are two fields that say ‘Phone Number’ - it will be difficult to set a visibility condition since both the fields have the same name.

Both of these fields ‘Phone Number’ will have different unique identifiers. You can check the unique identifier and then set the condition accordingly.

3. Visibility Conditions

Visibility Condition in the property for the ‘Subform’ is used to specify a condition.

If you apply any visibility condition, it implies that the ‘Subform’ will only be visible if it satisfies the condition that you have set.

Visibility condition can be set by specifying the condition - you can do that by clicking ‘condition not specified.’

For example,

You might create a Subform ‘Inspection Form’ which will be only visible if the user chooses ‘Yes’ option in the previous choice list ‘Did you carry inspection?’

Visibility conditions can help you control the type of input during the filling of a form by the user.

4. Validity Conditions

Validity Condition in the property for the ‘Subform’ is used to specify a condition.

If you set any validity condition, it implies that the ‘Subform’ will only be valid if it satisfies the condition that you have set.

Validity condition can be set by specifying the condition - you can do that by clicking ‘condition not specified.’

For example,

You might create a subform ’Manager Interview’ which will be only valid if the user enters ‘Yes’ in the earlier field ‘Was the manager available for the interview?’

Otherwise, it would be invalid and show an error message.

Validations can help you control the type of input during the filling of a form by the user.

You can also customize an error message that you want to display by typing the message in ‘Validity Error Message.’

This message will be displayed when the validity condition does not match with the given input.

The error message could be “To be filled only when the manager is available for interview.”
