PLEASE NOTE: This suggestion is for Dynamics CRM Online and Dynamics CRM 2016 or greater. There is no option in the below "Product Version" drop-down list.
There are many occasions where multiple fields need to be hidden and/or shown based on Business Rules. This can lead to a very long and complex Business Rule. This suggestion would allow a User with Customization access to create a Business Rule that can show/hide a Section (Tab) on a Form.
