# Create custom case fields

Create case fields so you add them to custom case layouts.

You can create custom case fields to:

* Map raw JSON fields from incoming issues.
* Display custom fields data in the **Cases** table.
* Create correlation rules that generate issues from XQL queries and map the output of the queries to custom case fields.
* Design custom case layouts that include custom case fields.

How to create a new custom case field:

1. Select **Settings** → **Configurations** → **Object Setup** → **Cases** → **Fields** → **New Field**.
2. Choose a field type and enter a field name. You can add an optional tooltip to provide users with information about the field.

   If adding a grid, see [Create a grid field for a case](/cortex-agentix/configure-cortex-agentix/cases-and-issues-configuration/customize-case-fields-and-layouts/case-fields/create-custom-case-fields/create-a-grid-field-for-a-case.md).
3. Save your changes.

Custom case fields can be exported and imported. To export a single custom case field, right-click on the field in the fields table, and select **Export**. To export all custom case fields in a single JSON file, click the **Export All** button above the fields table.

After a custom case field is created, it can be edited, deleted, or exported by right-clicking on the row. The field name and field type cannot be changed after the field is created.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cortex-docs.paloaltonetworks.com/cortex-agentix/configure-cortex-agentix/cases-and-issues-configuration/customize-case-fields-and-layouts/case-fields/create-custom-case-fields.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
