Views Global Filter
Use Views Global Filter on sites that feature multiple Views. You want
the views to be driven by the same filter selection, for instance a
country, a date range, a search term or even proximity to a post code.
These views may be on the same page or scattered across several pages
on your site, however you want to offer the visitor the convenience of
setting the filter for all these views only once, for instance when
they first land on your site. Views Global Filter implements the
picked once, operates site-wide (POOS) principle. This means you can
place anywhere on your site a selection widget (drop-down, check boxes
etc) to globally filter all or some of your views. When the user picks
a value from the global selector, the value is invisibly passed as a
contextual filter to whatever views you like, even when these reside
across multiple pages. This avoids you having to duplicate filters and
avoids the visitor having to re-select their choice as they go from
page to page.
