* You need "Update Permission" to save the layout after changing the position and size of the added perspective.
## Operation Procedure
1. Open the target "[Dashboard](/en/manual/dashboard)".
1. From the "Manage" menu, click "Dashboard Management".
1. Click on the "Dashboard Parts" tab.
1. Click the "Create New" button.
1. Enter the appropriate settings and click the "Add" button.

## Asynchronous Loading
If you want to display dashboard parts with asynchronous loading, check the "Asynchronous Loading" checkbox on the "Dashboard Parts" tab.
|Asynchronous Loading|Dashboard Display Behavior|
|:-|:-|
|Checked|Display data will be acquired for each part. Parts will be displayed in order starting from the parts for which data acquisition has been completed.|
|Unchecked|Display data for all parts will be acquired at once. The screen will not be displayed until all data acquisition is complete.|
### Asynchronous Loading Completion Event
If asynchronous loading is enabled, the content of the part will be updated when asynchronous loading is complete. If you use a script to customize the content of a part, such as creating a screen within a part using custom HTML, write that processing in the event (after_set_DashboardPart) that is executed when the loading of the part is complete.
##### JavaScript
```
// Event triggered when the asynchronous loading of the dashboard part is complete. {n} contains the part's ID.
$p.events.after_set_DashboardPart_{n} = function() {
// Write the process to customize the content of the part here.
};
```
