Internal id element

The internal ID element is automatically added when you create a new list.

It renders a hidden field with the current record's numerical id.

This id auto-increments for each record you add

In the list's database table this field is also set to be the lists primary key, ensuring that each record has a unique identifier.

If you wish to create a more readable identifier then you should leave the internal id as it is and create a new calc element.

Say we want this field to show the values 'application-X' where X is the internal id value then enter the following code into the calc element's 'calc' field:

Finally, ensure that the 'Only Calc on Save' option is set to NO, and then save your element.
