Prestashop 1.7.4.4 Category description, show more or less

[manuel194]

Hello all,

I'm new in prestashop.

I need a little help with the categories and subcategies descriptions.

I would like to add long texts in the descriptions but i need the show more button after the first 3 rows and temporary hide the other part of the text.

Because of big ammount of data i can't use codes which requires to introduce manually in every categories/subcategories in source code a div class and hide it and paste the text inside of that div class. This requires too much time to make it in every single description.

So basically i want to truncate example at 350chars and with a link or button display the rest of the text.

Thank you,

Emanuel
