# Custom fields

Custom fields let you add extra data fields to your assets to capture information that Lansweeper doesn't collect by default. There are two types:

- **Basic custom fields**: Fields you define and populate manually.
- **Derived fields**: Calculated fields that evaluate an expression across your asset data. See [About derived fields](/docs/about-derived-fields).

The steps on this page cover basic custom fields.

## Create a custom field

1. Go to **Assets** > **Fields** > **Custom fields**.
2. Select **Create a custom field**.
3. Enter the name of the custom field.
4. Select the **Type** of custom field. Depending on the type, you may also need to enter **Selectable options** or **Currency**.
5. Enter the **Field description**.
6. Select **Create**.

## Edit a custom field

1. Go to **Assets** > **Fields** > **Custom fields**.
2. Select the custom field, then select **Show Actions**.
3. Select **Edit** to revise the custom field's:
  - Name
  - Type
  - Selectable options
  - Field description
4. Select **Save**.

## Delete a custom field

1. Go to **Assets** > **Fields** > **Custom fields**.
2. Select the custom field, then select **Show Actions**.
3. Select **Delete**.

              Custom fields across linked installations

              

If you've federated custom asset data from a linked Lansweeper Classic installation, your custom fields are consolidated in your site and follow specific matching rules. See [Manage Lansweeper Classic custom asset data from your site](/classic/docs/manage-custom-asset-data-from-your-site).
