4-10-2 Component Layout
Let's place the components.
Since this layout is designed for reference data, relevant components (reference data, etc.) can be placed.
Each component has a "Rendered" property. The True/False setting will control the components' Show/Hide settings.
The "Custom Setting" of Salesforce's default feature can control Show/Hide ability by profile or by users.
Setting -> Application Setting -> Implementation -> Custom Setting.
*Note1: Select "Hierarchy" on Custom Setting to use this feature.
*Note2: Select "Check Box" as data type for Custom Field to use this feature.
Here is the script for Custom Setting property value.
{!$Setting.SettingName.FieldName}
SettingName :API referral name of Custom Object Setting (e.g.: SVEDashboard__c)
FieldName :API referral name of Custom Field (e.g.: ChatterFeedDisplay__c)
