Oleg outlines how to set it up like a business rule. I also outline how to handle the lookups request to load it's data source and then create the filter t that time (which makes it easier to refer to other values in the page that you want to use in the filter).
just read the 8.0.7 release notes ""Advanced business rule conditions. It is now possible to set up more advanced business rules using system settings and system variables in business rule conditions. For example, you can set up a rule that displays the [ Results ] field if the current user is the record owner.""
