How to load all remaining content of a view after clicking a "load more" link?
You need Views show more module with ajax under views advanced setting. This module provides Initial item selection option, and rest of the item you can put in the section of on-click.

Steps-


Download and enable the module.
Select show more pager in the Pager section as shown in the image. Then go for setting for that. Now in my case I took 15 items, and I want to initially show 5 items and on clicking rest of the item. So I did put 5 under the Initial items and 10 items under Items to display as shown in second image. And under Animation section select Scroll to new content. Save this, so pager setting ends here.
Under advanced setting of views enable, Use Ajax: Yes
