Page length limite

Hi,

Good morning every one 

I will simply explain my problem 

I want to shorten the length of my page and have the customer click "load more" if they want to see more of the page.

I don't think this is possible with an entire page. But you can use this plugin to load more sections: https://www.sqsmods.com/expand-20

You can then use this at multiple points on the page to 'load more' content.
