Hi @Kumar9024021 ,
Could you please share a bit more about these fields that you mentioned? Are they individual fields/controls or all fields existed within a Edit form?
If these field that you mentioned are existed within a Edit form, I think the Custom data card could achieve your needs. You could consider add a Custom data card in your Edit form, then re-order it to the Top as below:

Then add a Label within the Custom data card, set Text property to following:
Search Request

Then re-order data cards in your Edit form, it would display as below:

In addition, you could also consider enable the "Container control" functionality in your app, then you could add your field controls into this container control.

Then add a Container control within your app:

Then you could add your "Search Request" Label and all your field controls into this Container control. You could also change the Border color of this Container control to meet your needs.
Best regards,
