Create category list without module

[klemonnier]

Hello Prestashop Friends,

 

I want to create a list of product categories in the header of my website (for all layouts and pages) and I don't want to use a module. My module categorytree is already used.

 

I started a code but I have 2 problems.
First one, this code works only on product page. I can't see the menu in other pages.

Second one, I don't know how to get the URL. I tried $category.url or $category.link_rewrite and it s not working.

<ul>
{foreach from=$categories item="category"}
	<li><a href="">{$category.name}</a></li>
{/foreach}
</ul>

I hope someone can help me. I'm in Prestashop 1.7.1.1.

Thanks
