La spécification d'un nombre de valeur négative affichera le fil d'Ariane jusqu'au niveau supérieur et ignorera la page par défaut.
Explication de CG en version originale

the alias is 'home' (it's a case sensitive thing).

let me describe how it works using this hypothetical page tree

1 Home (id=1,alias=home)
1.1 Page 1 (id=2,alias=page-1)
1.1.1 Page 2 (id=3,alias=page-2)
1.2 Page 3 (id=4,alias=page-3)
1.2.1 Page 4 (id=5,alias=page-4)
1.2.1.1 Page 5 (id=6,alias=page-5)
2 Page 6 (id=7,alias=page-6)
2.1 Page 7 (id=8,alias=page-7)
2.1.1 Page 8 (id=9,alias=page-8)
2.2 Page 9 (id=10,alias=page-9)
2.2.1 Page 10 (id=11,alias=page-10)
2.2.1.1 Page 11 (id=12,alias=page-11)

If my current page is "page-4":
{nav_breadcrumbs}
should display: Home >> Page 3 >> Page 4
{nav_breadcrumbs root=-1}
should display: Home >> Page 3 >> Page 4
** "home" is a direct ancestor of my current page.
{nav_breadcrumbs root='page-3'}
should display: Page 3 >> Page 4
** page-3 is in the output path, so it is the first we will display.
{nav_breadcrumbs root='page-9'}
should display: Home >> Page 3 >> Page 4
** page-9 is not in the path, so nothing to stop at.

if my current page is "page-10"
{nav_breadcrumbs}
should display: Home >> Page 6 >> Page 9 >> Page 10
{nav_breadcrumbs root=-1}
should display: Page 6 >> Page 9 >> Page 10
** the home page is not automatically added.
{nav_breadcrumbs root='page-3'}
should display: Page 6 >> Page 9 >> Page 10
** page-3 is not in the hierarchy path, so n othing to stop at
{nav_breadcrumbs root='page-9'}
should display: Page 9 >> Page 10
** page-9 is in the hierarchy path, so that is where our first path is.
