Add field as reference field

I have tried more than 30 minutes to achieve to create a field as another field reference. I can’t get the any tip for any document on google. Give any referral document or page link to achieve the same.

Hey @babu.ankaian0311,

We have documentation that covers this: References | Contentful Help Center

@harshil.agrawal , Thanks for your kind support and guidance.

I know this one-to-one reference and one-to-many reference concepts.
These are referencing one entry to another entry… But I need to achieve one entry field to another content type field reference.

Like: For Example:

Product (content type)
title - short text
description - long text
price - integer

Category (content type)
title - short text
description - long text
icon- image

Here, I need category content type title field as
Product content type - category reference field

Expecting Result:
Product (content type)
title - short text
decription - long text
price - integer
categories - reference (title field of category content type)

Please kindly help me out here asap.

Thanks & Regards,
Babu A.
