Step 2 - Install the Partial Entries Add-on

Navigate to Forms->Add-ons and install and activate the add-on.

Step 3 - Activate the Partial Entries For Your Form

Step 4 - Add Event Meta to Your Form

While editing your form, click a form field and go to Advanced. You'll see that you can input an event category, action, label, and value.

You can put in whatever you want, but make sure it matches your Google Analytics goal.
