Override or disable default titlebar

Hi,

i'm a new vanilla forum dev user.

I'm trying to develop a custom theme; i have already read the theming docs in the official knowledge base.

Here is what i did: i copied "addons/themes/theme-foundation" as "addons/themes/theme-custom", then changed key, name and description in my addon.json. I have also customized my package.json.

After building the assets i applied my theme: everything worked fine.

The forum will be integrated in an existing website, so i need to use the same menu navbar as the whole site. I'm tryng to override (or disable) the vanilla titlebar, but i can't find documentation about this.

Is possible to do so?

Thanks
