How To Add "readmore" Button For Cms Page

[miladfathi]

Hi,

 

I want to add ReadMore button for my CMS so when you click on it, it will expand the hole page and you can read the rest of the page.

The reason I want to add a read more button to my CMS page is because I have a long page and I want the reader to click on the button and expand the page as he/she reads trough the CMS page.

I searched online and but I couldn't find any module for it. I know one person asked this question on prestashop forum but he didn't upload the module or he didn't explain how to add it.

 

Your help is appreciated.

Thank you
