Answer 1

From what I can see, you are recovering all the data without paging it.
You must paginate the data using the paginate(#elements_per_page) directive in your query, where #elements_per_page is the number of elements you want to display per page.
For example:
$elements = Elements::select('*')->paginate(10);
and in your blade view you can retreive pagination links after the closing table tag in this way: {{ $elements->links() }}
