Add New Section with some field in Customizer

Hi @amit107051,

I am not quite sure if I understand you by Add New Section. Anyway, these docs should help you to get work with the Astra Header Builder on Desktop and Mobile:

• https://wpastra.com/docs/create-header-with-header-builder/
• https://wpastra.com/docs/create-mobile-header-with-header-builder/

I hope it will help.

Kind regards,
Herman ??
