Do you already know your respondent’s name, email, or other information? With Hidden fields, you can feed this right into your form so respondents can skip filling out this information. 

Mark any Email, Text, URL, Dropdown, Priority, or Number Custom Field as hidden, and they will be captured through your unique URL or embed code.

Feature availability and limits vary by plan and user role. Learn more.

Set a field as hidden

To set a field as hidden in Form view:

1. Edit a Form.

2. Hover your mouse over an email, text, URL, dropdown, or number field in your form.

3. Click the ellipsis ... menu.

4. Check Hidden field.

Form URL structure

You'll need to append a valid value to the end of a Form's public URL to fill out hidden Custom Fields. Forms will fail to submit the value that is input doesn't exist.

The URL will use the following format:

Public URL + ? + field label + field value

For example: https://forms.clickup.com/f/ad-4679/NN9MMFH6QOKWVJUXUT?Source=ClickUp%20Form

In the above example, this Form view includes a dropdown Custom Field called Intake Source, which is labeled Source on the Form. "ClickUp Form" is one of the values in the dropdown Custom Field.

When you copy a Form link, you'll see any hidden fields added to the end of the Form's URL automatically. Prior to pasting the URL into the search bar, replace the xxxxx placeholder text with a valid value.

When a field name or value includes spaces, use %20 between each word.

Pass a line break

To pass a line break on your Form, add %0D%0A to the URL. 

Get the Public URL

1. Click Copy link to obtain the public URL for your form.
2. Replace the xxxxx placeholder with a valid value.

1. Click the dropdown arrow next to Copy link
2. Select Copy Code.
3. Edit the src tag of your embed code to include the field label and value.

Add values to the Form URL

Field label and values are case-sensitive, and in order to add multiple prefilled Custom Fields you need to separate them with a "&".
