This is related to Gabor's ticket: *https://jira.greenpeace.org/browse/PLANET-2836* 

• As a web editor, I want to insert values on the Form Backend so that I can better identify conversions on Analytics.
• As a data analyst, I want to start tracking the signups on the Planet 4 pages and be able to identify what kind of conversion or campaign the form is related to. 

Part 1: Create text or dropdown fields on the Form Backend

The values chosen by the user will be sent through dataLayer.push method

• Campaign name [dropdown field with this list
• Basket name [dropdown field with this list
• Scope [dropdown field with this list
• Department [text field]

Part 2: Send a dataLayer event with parameters defined on the backend:

Embed an onclick dataLayer.push in the submit button code that will send an event and parameters (values) the were input by the user:

dataLayer.push({

 'event' : 'petitionSignup'

 'gcampaign' : ‘[value defined in Campaign field]’,

 'gBasket' : ‘[value defined in Basket field]’,

 'gScope': ‘[value defined in Scope field]’,

 'gDepartment': ‘[value defined in Department field]’,

 });

This would automatically collect the "submit" event, and send it to Google Analytics using the GTM configuration.
