# Default values for new items

> [HTML Version](360022129191.html)

The app can be configured so that users can create items of another app with automatically pre-filled values on its form. This would allow, for example, users to create related documents on a contract form and fill in their fields according to the contract data.

For this purpose, fields of the **App**-type are used with the **Default values for new items** option. For a full description of all available settings, read [App data type](app-data-type.md).



## Set up values for the fields of new items

Let's look at how to set default field values, using contracts and related certificates as an example:

1. In the **Contract** app [form settings](360009918011.md), add a field of the **App** type and select the **Certificates** app in its settings.

2. Click **Default values for new items**.

3. In the window that opens, set up the fields that you want to be filled out automatically. Select a field in the **Certificates** column and add a corresponding field in the **Parent** column. In our case, the parent item is the contract.   
  
For example, the **Certificates** app has the **Contract number** field that needs to contain the number of the corresponding contract. Add this field to the **Certificates **column. In the **Parent** column, select the **Contract number** field of the **Contracts** app.    
  
You can also specify a specific value so that it will be the same for all created items.

4. Complete the field settings and click **Save**.

Now, users can create related certificates on the form for a new or existing contract, and the specified fields will be pre-filled automatically.

If you want the certificate to be added to the system only with the contract, you can also use the **Bound app** option. For more information, see [Bound apps](360020016471.md).



## How default field filling works

To pre‑fill the fields of the created certificate based on the contract data:

1. Open the contract [creation or editing](360016427291.md) form and ensure that the fields from which the data will be transferred to the act are filled.

2. To the right of the **Certificate** field, click **+ Create**.

The certificate creation page will open. All the selected fields will be pre-filled according to the contract’s data.**(hmfile_hash_58de0999.png)**

3. Add a file and click **Save**.

The created certificate will appear in the **Certificates** app and will be displayed in the contract page.
