Optional signing fields

Signing fields can be set to optional, which means they don't have to filled-in in order for the signing to be completed.

Here's how to do so:

1. Select the field that you want to make an optional field. On the right side, you will see the options.
2. Underneath recipient and client, you'll see a toggle option that says optional field. Toggle this option to enable the field to become an optional field. This will then make the field transparent.
