Validations can be added to existing fields in a content type.
To get started adding validations to existing fields:
Log into the web app.
Click the Content Model tab, then choose an existing content type.
You will be brought to the list of fields for your selected content type. Click ‘Settings’ on the field of interest to open the field editor dialog, then choose the Validation tab at the top of the dialog to show the available validation options for the field type.
Different fields have different validation options that are specific to that field type. For example, the Short Text field allows constraints around uniqueness, being required, matching/prohibiting patterns, length, and only allowing predefined values. Additional options become visible when a validation is selected.
Fields can be set to have a specific appearance, to help guide editors while working on content. For example, if a text field must match a predefined list, it may be easier to provide the editor with a dropdown list or a radio button list with those values.
To set the appearance of a field:
Click the “Appearance” tab of a field to reveal the different display options
Select the desired appearance. You can also add help text to a field on this tab.

3. Click Save to close the field editor dialog once you are happy with the validation, then click Save in the top right corner of the content type editor to update the content type.
IMPORTANT: Changes will not take effect until the content type has been saved
