Child theme not visible

The problem is in the folder structure. The child theme should be in the same directory as the parent theme. That is:

E:\xampp\htdocs\wordpress\wp-content\themes\panoramic-child

Not:

E:\xampp\htdocs\wordpress\wp-content\themes\panoramic\panoramic-child

Also you don’t need this line in the header comment of a parent theme’s style.css:

Template: panoramic

It is used only in a child theme.
