Add text and button to header section

Hi there,

Would that be just for the desktop or it should appear in your mobile header as well?

Just the desktop version for now.

You could try this solution:

Thanks Ying. What about adding text (Phone numbers) to the menu line as shown?

Just like adding other menu items using custom links, you could use # as its link, add phone number into Link text.

No problem :)
