Layout Rules

Designer > Objects > {object} > Forms > {form} > [Layout Rules]

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>

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.

Considerations

• 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 of a Record
• To be available for use in a Layout Rule, the field must not be hidden in the layout.
  (If it should be hidden at times, then hide it using a Layout Rule.)
• Multi Object Lookup fields cannot be used to specify criteria for a Layout Rule.

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.

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
