Additional fields (FKA Custom fields) can be used to gather all sorts of information from your event attendees! Use this feature to gather critical information during the signup process. Get answers to questions like "Do you need lodging?", "Do you have food restrictions?", "What is your member number?" or "Do you have any accessibility needs?". 

Additional fields will always appear below the standard signup field, like below. Read on to learn how to configure these fields for your events!
​

Additional fields will allow your organization to collect key pieces of additional information from supporters, members, and volunteers on event signup pages.

Each organization will have its own library of Additional fields, which, as an admin of the organization, you can manage and add to.  Event creators will be able to choose up to two fields from the library to add to each event.
​

As an admin, you can manage and add Additional signup fields to your organization’s library. To get started, navigate to the "Additional fields" tab in your dashboard.

To create a new signup field, click "Create new field."

For each field you want to create, you will need to fill in the following details:

Click "Add to library" when you’re done to add the new field to your organization’s field library.

After creating Additional signup fields, they will be visible in the Additional fields section of the dashboard (for admins only).

You can edit an additonal signup field by clicking the "Edit" button on any custom signup field, and remove a field by clicking the "Remove" button. This will disable that field as an available option for other event creators, and remove the field from any previously-created events.

Once additional signup fields have been added to the Field library, admins and organizers will be able to add up to two additional fields when creating and editing events:

Mobilize signup forms already collect essential contact information like name, phone number, zip code, and email address, which will be pre-filled for any supporter who has taken action on Mobilize previously. Additional fields will always appear on the signup page under these standard fields.

If it is absolutely necessary that supporters fill out the field to take action, you can check the box 'This field is required on the signup page' when you add the field to your event, as seen below:

Supporters will not be able to complete their signup without filling in the required field or checkbox, and will not have the option to "sign up in one tap" for an event with required fields in automated event suggestions (including via SMS).

To avoid supporter drop-off, we recommend only making a field required when absolutely necessary for your event or action. A required field will look like this:

Additional fields can be removed from an event at any time, even if data has been collected. Any data previously collected will still be available in the CSV exports.

Data captured through additional fields can be downloaded via the Signups CSV export. Each additional field will appear as a separate column in the CSV export.

Information collected through additional fields will also be visible for each signup on the timeslot details page:

Additional fields will not appear on partner events that you promote on your feed.
​
Additional fields will, however, appear on your events when they are promoted by partners, so we recommend checking that your field labels would be understood if they appeared on an event in a partner's event feed.
