The Text Preview plugin can apply a custom class to the text preview layer based on the ‘Field Class’ setting in Add-Ons Ultimate.
To add a custom class to an add-on field, enter the class name in the ‘Field Class’ setting:
This class will then be applied to the text preview layer with the apaou- prefix. So a custom field class called models-field will be added to the text preview layer as apaou-models-field.
