How to check all checkboxes in a Views exposed filter by default? I'm using the Views and Better Exposed Filters modules to allow users to select age ranges like this:



This view functions as a search page.  However, users are confused because if they simply hit Apply, all age groups are searched even though no age groups are checked.  For this reason, I would like to show all age groups as selected by default to make it clear that all age groups are searched by default.

How can I do this?
If you click on the filter in the Views admin UI to get to the "Configure filter criterion" popup, and then select all of the options for the filter like so:



Then they appear ticked by default when you access the View page.
