Guys Thanks I found the solution

Steps to Add a Hidden Field in JetFormBuilder:

1. Open Your Form:
   Go to JetFormBuilder > Forms and edit the form you’ve created.
2. Add a New Field:
   Click on Add Field.

Set the field type to Hidden Field.

3. Field Settings:
   Under “General”:
   Field Name: For example, use category

Default Value:

If you want to store the category ID, enter something like: 15

If you prefer the slug, enter: news

Under “Advanced”:
Optionally, you can assign a custom CSS class for styling or identification, but it’s not required.

🎯 Result:
This will store your selected category (e.g., news) as part of the form data.

Users won’t see it or be able to change it.

The value will be submitted alongside the rest of the form fields.
