Layout Rules provide the ability to create dynamic Forms that adapt and offer additional options as data is entered.
About Layout Rules
As data is entered into a form, Layout Rules can be used to:
- Hide or show fields or entire sections of a form.
- Disable or enable fields
- Assign a value to a field
- Hide or show values in a Picklist
- Hide or show values a Button
- Display a message
Sample use cases:
- Show a discount button when an amount reaches some value
- Hide a section to prevent access to data until after a specific date and time.
Working with Layout Rules
Users that have the Customize Objects permission can edit Layout Rules
Layout Rules use an IF...THEN...ELSE model to customize a form layout:
- IF some <condition> is TRUE
- THEN do a <thing>
- ELSE do another <thing>
- THEN do a <thing>
- The <condition> is written as a Formula Expression, which can make use of most of the fields in the record, as well as some related fields.
Note:
A field can be referenced in either:- a. A section for which Show Empty Fields in View has been disabled
(using Advanced Options in a Section), or - b. A Layout Rule condition.
But it cannot be referenced in both places.
The Reason: If the field is empty, the server removes it from the page. The Layout Rule, meanwhile, is a JavaScript function in the page. When the Layout Rule tries to test that field, an error occurs.
- a. A section for which Show Empty Fields in View has been disabled
Considerations
- Layout rules follow an IF...THEN...ELSE model
- Each Layout Rule can include multiple actions
- Actions are executed in the order in which they are displayed
- Actions can be added, edited, deleted or reordered
- Sections can be opened based on a condition
- A condition can be applied on Add, View or Update a Record
- Multi Object Lookup fields cannot be used to specify criteria for a Layout Rule.

Layout Rule Builder
The Layout Rule Builder has three sections:
- IF Section
- Specify the condition that will trigger this rule
- Create a Formula Expression (using <FIELD_NAME> <OPERATOR> <FUNCTION>) that evaluates to a TRUE/FALSE state
- The contents of the Field list may differ based on the object
- If the condition resolves to TRUE, take the action associated with the THEN condition
- If the condition resolves to FALSE, take the action associated with the ELSE condition
- THEN Section
- Optionally, create action(s) to take when the expression is TRUE; Actions are displayed in rows which can be added, edited, deleted or reordered
- ELSE Section
- Optionally, create action(s) to take when the expression is FALSE; Actions are displayed in rows which can be added, edited, deleted or reordered
