Apply Sales VAT per category and display per line itme on invoice

Hello Good people. We are running the VM of erpnext V5; we have been able to take stock counts and make entries and manage our inventory; we have also applied a tax globally on all items; what we desire is to apply the tax on specific groups for instance food (0%), electronics(5%). And we’ll like the tax to be displayed only on taxable items so if an invoice contains only food; the tax should never display. Is this possible?

You can set Item Tax
