Mobile : replace breadcrumb by a simple link to last category

[floleo46]

Hello,

I'm on prestashop 1.7.6.4

On mobile, on category page, i'd like to replace the breadcrumb by a simple "back" link that links to the parent category.

Let's say my breadcrumb is : Home - Category A - Category B - Current category

I'd like the link to do :

< Category B

 

In css i already did this when max-width:767px (and the opposit when min-width:768px)

#category .breadcrumb {display:none;}

#category .replacebread{display:block;}

Can you help me ?

Also, on a product page i thought i had the good link but it doesn't work : how to link to the main category of the product, and show the name of this same category ?
