This feature allows you to limit how many and what type of characters are accepted in a form field.


Input masks are a great way to guide your completers towards what kind of data you need them to provide. Input masks can only be added to single line input fields.

Click on a single line input field that you'd like to add an input mask to.

Your field configurations will open on the left side of your screen. Scroll down until you see the Input Mask box under the Settings section.

In this box, you are going to type in a structure that matches what data should be inserted in this field. For each numeric character you'd like them to include, you will represent that with a 9. For each letter you'd like them to include, you will represent that with an A (must be a capital A). You can also include any special characters that support the way you'd like this data to be presented.

For example, if you'd like your completers to type in a phone number, you would type (999) 999-9999 as the Input Mask. When your completers complete this field, they will only be allowed to input 10 numbers and the parentheses and dash will automatically appear.

If you'd like your completers to type in the initials of a state, you would type AA as the Input Mask. When your completers complete this field, they will only be allowed to input 2 letters.

If you'd like your completers to type in a time of day, you would type 99:99 as the Input Mask. When your completers complete this field, they will only be allowed to input 4 numbers and the colon will automatically appear.

Be sure to frequently click the purple Save Form button in the top right corner to ensure that your changes have been saved.
