Problem:

I am trying to use the default_label attribute with the [wpv-control-postmeta] shortcode to display a default "All" option for a checkbox custom field. Despite following the documentation, the default_label attribute isn't functioning as expected, and adding the option through jQuery is proving complex.

Solution:

Checkbox fields do not natively support a "select all" option via the default_label attribute. Instead, add a custom checkbox labeled "All" manually and use the wpv_filter_query hook to modify the query when this option is selected. Check the $_POST object to identify when "All" is selected and update the query args accordingly.
