Use declarative actions to resize a modal in your workspace.

## Antes de Iniciar

Role required: admin

## Por Que e Quando Desempenhar Esta Tarefa

If resizing isn't required for all record page modals, use declarative actions to resize individual modals.

Declarative actions take higher precedence than system properties.

## Procedimento

1. Navigate to AllDeclarative ActionsRelated List Actions.
2. From the Action Assignments list, select a related list action.  
   An Action Assignment record opens.
3. From UX Add-on Event Mappings related list, select the event mapping for opening a modal.  
   A UX Add-on Event Mapping record opens.
4. In the Target Payload Mapping field, enter the following snippet under `"container": {`.  

                                       "resizableConfig": { 
        "enableResizable": true 
       }, 

5. Specify the modal's default size by appending the following snippet.  

       "customSize": { 
                   "height": "590px", 
                   "width": "1500px" 
               }, 
        
       "size": { 
                   "type": "JSON_LITERAL", 
                   "value": "custom" 
       }

6. Select Update.
