如何返回AllSubSections（所有级别）的所有 ID

class Section extends Model
{
    public function Ads()
    {
        return $this->hasMany(Ad::class);
    }

    public function AllSubSections()
    {
        return $this->SubSections()->with('AllSubSections');
    }

    public function SubSections()
    {
        return $this->hasMany(Section::class);
    }

    public function Parent()
    {
        return $this->belongsTo(Section::class);
    }
}

我目前正在做的是：

$section = Section::where('name', 'Properties')->first();
$subSections = $section->AllSubSections;
$subSections->pluck('id')

但它只返回第一级而不是所有级别。
