Short Text Fields have a field setting called System Default. System Default allows you to dynamically pull in information based on account data collected by GoCanvas that is specific to the user who is logged in. An example would be automatically pulling the first and last name of the user who is currently filling out an App.
The System Default setting can be found by clicking More in your Field Settings:
System Default options defined
System Default defaults to None, that is, the short text field will be empty when the user arrives at the screen. The other options that appear are all specific to the user who is currently logged into GoCanvas. They are:
Username: The email address used to log into GoCanvas.
Company Name: The name of the company registered to GoCanvas, as defined in the Billing Info settings (under Billing Contact).
First Name: The user's first name as provided when creating their account.
Last Name: The user's last name as provided when creating their account.
Full Name (First Last): The first and last names provided when creating the account.
Why is the System Default field grayed out for me?
If you have a Field Style chosen for either email or number, you cannot set a System Default for that field. Both of those settings indicate the type of data you can to collect in that field, and having information appear automatically is incompatible with adding that data.
