Add fields from the table, in our case it is the Make and Model
Important: The names of the fields must be unique, i.e. in the transaction or in the company or in the contact there should be only one field with the name of the Brand and one field with the name of the Model. If there are 2 fields with the same name in the transaction, then the widget will not be able to find the field you need, similarly, if there is a field with the Brand name in the transaction and there is a field with the same name in the company /contact, then the widget will not be able to find the field you need.
When you click on the Brand field, suggestions of car brands will appear or start entering the brand in the field. After selecting a brand, click on the Model field and the models of the selected brand will appear
