I have a Views grid that can display anywhere from 0 to dozens of results. I want to display a 3 column, 2 row grid with a pager that will always show 6 cells regardless of how many results my filter gives. How do I do that? Also, I can't find the option to display the View even if there are no results. Where is that?
You can take a look at Views responsive grid. I'd suggest using it over the built in views grid because it splits up your rows/columns in a more manageable way.
The functionality you're looking for is built into views, under pager. You would need to set it to use a pager as well as display 6 results.
The section under Advanced -> No results behavior is what you are looking for.
