function global_filter_options_none in Views Global Filter 8

Same name and namespace in other branches

1. 7 global_filter.widgets.inc \global_filter_options_none()

Override of the theme_options_none() function.

In addition to the regular options as returned by hook_options_list, the Options module will always prepend a 'none' for non-required fields, whether appearing as a single or multiple-select. We can't intercept this process. We could make the select mandatory and then prepend a 'none' option ourselves, but then we end up with a red asterisk for a select that isn't really mandatory...

Until I can find a way to determine if this is a global filter context, I'll switch this feature off for global filters driven by field widgets.
