Put custom code before and after menu

Trying to ad logo image before main menu (off-canvas menu)and fav icons  after main menu through sparky framework. With j3 everything was working fine but after updating in j4 last year and j5 now when you save the code the before and after box not working and remains empty 

Hello,

There are separate template files for J3 and J4. The template files for J3 don't work on J4 after the upgrade and you need to re-download and re-install the template files.

On the other hand, after upgrading from J4 to J5, usually everything works smoothly. However, there are also template files for J5 that are slightly different than J4 template files.

Regards,
Milos
