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.
Note	Here you have the option of adding some text to your upload area that gives users additional information, such as the maximum file size allowed in megabytes, for example. By default, this text is shown underneath the file upload area. You can include text formatting here by using markdown commands.
Text on upload button	Enter the text to be displayed on the upload button.
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.
Required field	Check Required field if at least one file must be uploaded when completing the form. An ‘*’ will then be added to the end of the label for the upload file field, marking it as a required field. Accordingly, users will be unable to submit the form if they have not uploaded a file.
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.
Multiple files	Check Multiple files if users should be allowed to upload more than one file.
Upload files automatically	Check Upload files automatically if files should be uploaded automatically as soon as users have selected them. If this box is not checked, then selected files are uploaded only when users actually click the Upload field.
Validation	You can adjust various settings if required: Error message Enter some text here for an error message that should be displayed instead of the standard error message. This error message is shown to the user if they attempt to upload a file that does not meet the criteria you have specified above. Max. file size (kB) Specify the maximum file size here. Max. number of files Specify how many files users can upload simultaneously here. Valid file types Specify which kinds of files users are allowed to upload. If you make no selections here, then any file type is allowed.
