Slugs with "/" and "-" characters

[cv-chameleon]

Hi all,

I'm saving slugs for nested categories. For perfomance reasons I save the combined slug of the nested structure to the slug field.
I also want a "-" character to replace spaces in the slugs.

So, for example, what I want in my slug field for a 3rd level category is {'nl': 'dranken/wijn/rode-wijn' ,'en': 'drinks/wine/red-wine'}.

What I'm able to do now is dranken/wijn/rode/wijn while using ->usingSeparator('/');.

But if I use ->usingSeparator('-');, my slashes are removed from my full slug.

This is my full code:

public function getSlugOptions(): SlugOptions
    {
        return SlugOptions::createWithLocales(config('app.locales_short'))
            ->generateSlugsFrom(function ($model, $locale) {
                return $this->createSlugs($model, $locale);
            })
            ->saveSlugsTo('slug')
            ->usingSeparator('/');
    }

public static function createSlugs($model, $locale): string
    {
        $list = [];

        if (!empty($model->parent)) {
            $list[] = $model->parent->slug;
        }

        $list[] = Str::replace(' ', '-', $model->title);
        echo implode('/', $list) . PHP_EOL;
        return implode('/', $list);
    }

Thank you for helping out.
