Use declarative actions to resize a modal in your workspace.

## Vorbereitungen

Role required: admin

## Warum und wann dieser Vorgang ausgeführt wird

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.

## Prozedur

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.

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" 
       }
