How to put toolbar on top but after the header?

I have a top Navbar, I want below of this, to put top tabs, like top toolbar, but I need it to be below the Navbar (header). What I get when I use:

<Toolbar
      tabbar
      labels
      top
      slot="fixed"
    >
...
</Toolbar>

Is the toolbar above the header and only by then, the header will appear.

How to fix this?

have you try with subnavbar? https://framework7.io/docs/subnavbar.html

It should work as it is, check Kitchen Sink toolbar examples, top toolbar/tabbar sits below the navbar
