How to add store data in Google.Analytics when tracking the application form?

Question

Google Analytics

Good afternoon, colleagues.
There are application forms for the car.
We track them by onsubmit="ga('send', 'event', 'Forma1', 'otpravka')"
Next to the form there is an indication of the car dealership that has this car. The tag with car dealerships has a unique ID, for example "autosalon1"
What parameter do I need to add to the anatilix code so that requests are distributed by car dealerships in the Event reports?
Thanks in advance.

Answer 1

At us in Universal Analytics, something like this is implemented through dimensions.
In the analytics settings there is such a Dimentions section. There you need to create a new one, for example dimention1.
Next, in the tracker code, add
ga('PageTracker.set', 'dimension1', 'autosalon1');
As a result, it will be possible to see this dimension by making a cut (through Segments) along it. Here. If I understood the question correctly :)

Answer 2

When generating the event sending code, you need to set up ID substitution in the
onsubmit="ga('send', 'event', 'Forma1', 'autosalon1')" code on the server side. Though it is possible and in the client.
