Sometimes, you will need a form field that only accepts numbers from your users. This might be a number between 1 and 10 as a rating for your service, for example, or an area value for a roof that must not be less than 80 m². In all of these cases, you can use the predefined Number form element and also specify the range for the number that can be entered into this form field.

The form element number is shown using the example of an order number.

Adding Number

  1. In the Structure area, click the green plus sign.
  2. Navigate to GeneralPredefined and click Number.
    You can now see the form field you’ve just added in the form tree.
  3. On the right, under Edit Number, you can now adjust the settings for your new form field as required.

Property Description
Label Enter the text of the label to be displayed next to the form field. By default, the label is shown above the form field.
Technical name Each form element that is added to a form is automatically assigned a unique name – known as the ‘technical name’ – by Formcentric. This name is based on the designator for the form element.
Alternatively, you can generate the technical name from the label. To do this, click New from label. Find out more about the technical name.
Here you have the option of adding some text to your form field that gives users additional information, such as instructions about filling out the field. By default, this text is shown underneath the form field.
Default value Enter a piece of text to be shown in the form field when users access the form. Alternatively, you can enter a variable here that adds a value automatically to the form field – such as the date. Find out more about variables.
Placeholder Enter a piece of placeholder text here. This text is shown greyed-out in the form field. This placeholder text disappears as soon as users start typing into the form field.
Field width Specify the width of the form element.
Display variant You can use this to add a CSS class from the website that you will be embedding the form into. The CSS class chosen here will be applied to the form element.
Alternatively, you can select one or more display variants to apply to the form element.
Read-only If you check Read-only, users will not be able to change the text in the form field. Use this setting if you want to enter predefined variables into this form field.
Required field Check Required field if this form field must be filled out when completing the form. An ‘*’ will then be added to the end of the label, marking this form field as a required field. Accordingly, users will be unable to submit the form or move to the next page (if this is a multi-page form) if they have not completed this form field properly.
Error message If you check the Required field box, an input field appears. In this field, enter the text shown to users if they try to skip filling out this form field.
Autofill The Autofill option is active by default. This involves form data stored by the browser being suggested as autocomplete options for the form field.
To improve the quality of these suggestions, you can tell the browser about the information that is expected for this form field.

  1. Shipping or invoice address
    Select Shipping or Invoice if this form field is part of a shipping address or an invoice address.
  1. Contact type
    Select an appropriate contact type here if users are expected to input a fixed-line or mobile phone number, fax or pager number, or an email address into this form field. Specifying a contact type will affect the selection offered to you for ‘Usage’ (see below). This field is optional and can be left empty.
  1. Usage
    Specify the kinds of information entered into this form field.

Deactivate autofill
Select Deactivate autofill to prevent the field from using autofill. This will also stop web browsers from saving the form field data. To do so, move the slider to the left, which deactivates autofill for this form field.
Validation You can adjust various settings if required:

  1. Error message
    In this field, enter the text shown to users if they do not fill out the form field according to the format you have specified.
  1. Min. value
    Specify the smallest number here that users can enter into this form field.
  1. Max. value
    Specify the largest number here that users can enter into this form field.
  1. Integers only
    If you check the Integers only checkbox, users cannot enter decimal values.
