# Custom Fields

> Add project-specific fields to test cases beyond the default test properties, set them individually or in bulk, and filter by their values.

**A custom field** adds project-specific information to a test case, beyond the default [test properties](https://testsigma.com/docs/arcus/v2/settings/test-properties/). Once a field exists, you can set it on test cases and filter the list by its values.

## Create a custom field

1. In the left navigation, go to **Settings > Custom Fields**.

2. Click **+ Add New**. The **Add new field in Test Case** panel opens.

3. Enter a **Field Name**. A **Description** is optional.

4. Select the **Field Type**.

5. (Optional) For a field type that offers choices, enter its options.

6. Click **Add**. The field appears in the **Custom Fields** section.

A field takes 1 of 8 types:

- **Text field**: a single line of text.
- **URL**: a link.
- **Text area**: several lines of text.
- **Date picker**: a date.
- **Dropdown select**: one option from a list you define.
- **Checkbox**: a single on or off choice.
- **Radio Button**: one option from a set you define.
- **Multi select**: several options from a list you define.

## Set a custom field on a test case

1. In the left navigation, open **Test Cases**, then create or open a test case.

2. In the **Test Properties** section, select the custom field values.

## Set a custom field on several test cases

1. In the left navigation, open **Test Cases**, then select the test cases to update.

2. Press `Command+K` and choose the custom field to edit.

3. In the **\** dialog, select or enter the value to apply.

4. Click **Update \ Test Cases**.

## Filter by a custom field

1. In the left navigation, open **Test Cases**.

2. Click **Filter by**, or press `Command+Shift+F`.

3. In the **Filter by** dialog, select the custom field to filter on. The list narrows to test cases matching your selection.
