Views Checkboxes

This module is used to change the form elements on Views pages with filter
forms.  Those forms normally use select boxes for single and multiple
selection drop-down inputs.  When this module is installed and enabled, the
single-selection drop-down can be changed to a list of radio buttons and the
multi-select box to a list of checkboxes.

You can define a limit on number of entries in the filter options.  E.g. if
the limit is set to 5 and there are 6 options, they will be displayed as a
list.  If there are 5 or less options they will be displayed with
checkboxes/radios.

Instructions:
Enable the module on the modules page and all users with the 'administer
views' permission will be able to access the admin page for 'Views
Checkboxes' and enable it.  Right now, it is enabled site-wide or not
at all.
