Setting fields to "Not Empty" indicates that the field value should not be empty. Fields with this attribute will be marked with a red asterisk on the upper left side of the field title.
When you set a field as unique, the value of this field cannot be a duplicate.
This feature is most useful when you want to make sure that you do not register the same thing twice in your database, for example, a username, e-mail or phone number.
With this configuration, when a user tries saving a record with the same value for a field marked as "unique", not only would the database prevent the user from saving, but will also display a pop-up window that includes a link to the original saved record.
You will see this option in subtable field settings (which is different from the "unique" attribute of general table field settings). Checking this option will block users from entering duplicate subtable field value in an entry, but subtable values in other entries are not subject to this restriction.
A field can be set as read-only, which means that the value of this field cannot be changed.
You can merge cells on your forms to span columns so that a single field may look wider.
This is significantly different than the method to adjust the height of a row or the width of a column.
If you're creating many entries with similar data, sometimes it's useful to clone the entry instead of rewriting data.
If you use the clone entry function often, you can set the fields that should not be cloned while cloning an entry as "do not clone".
When this configuration is set, the text in this field won't be wrapped.
Specifies that the value of this field will be displayed in barcode. (Code 128)
If you would like to generate other types of Barcode, such as a QR Code, you may use the Barcode field type.
Specifies that the field that will be hidden in the following:
1. Spreadsheet interface
2. Printer Friendly view
3. Excel download (and related export options)
4. Web embed form
The hidden field can be used to store values that you might need as constants, for formulas, and other use cases where the ability to view this value will not be practical for the user.
When used in a subtable, a hidden field will leave a gap, therefore while designing a form, please consider moving hidden fields to the end of the subtable.
You can add field instruction to help user enter data to the field.
The configuration for field instruction can be found from left panel under design mode > Field Settings > Other.
This will add a (?) to the field header, and your instruction will show when user clicks on the (?).
