I have a custom viusalforce page as part of a package that i'm developing. The package will be installed on a number of different Salesforce organizations. I require to hide certain parts of the visualforce page (input boxes) based on the organization using the package. What is the best way to accomplish this? I can hardcode it based on Organization ID but I'm not convinced this is the best way, as when clients refresh sandboxes the ID will change.
You should use rendered attribute on apex:input evaluating the org criterial:
<apex:input ... rendered="{!facility.Facility_Address_2__c!=''||render}" ...>
Where facility.Facility_Address_2__c could be the inline evaluation criteria of some org object.field value or render could be a flag set on controller evaluating a deeper criteria.
