Hide Activity Filter is Not Working

Hi @vantra117, Group document plugin is adding their filter with a different approach, not using BuddyPress actions. It will need to remove their actions and create it with BuddyPress approach. You can add following codes inside child theme functions.php to get it working.

$dropdowns = array();
$dropdowns = apply_filters('bp_group_documents_activity_filter_locations', array(
	'bp_activity_filter_options',
	'bp_group_activity_filter_options',
	'bp_member_activity_filter_options'
));
foreach ($dropdowns as $hook) {
	remove_action($hook, 'bp_group_documents_activity_filter_options');
}

foreach ($dropdowns as $hook) {
	add_action($hook, 'filter_bp_group_documents_activity_filter_options');
}

function filter_bp_group_documents_activity_filter_options() {
	$bp = buddypress();
	$filters_db = bp_get_option('bp-hidden-filters-name');
	$defult_activity_stream = bp_get_option('bp-default-filter-name');
	$nav_page_name = get_option('bp_group_documents_nav_page_name');
	$name = !empty($nav_page_name) ? $nav_page_name : __( 'Documents', 'bp-group-documents' );
	if( is_array( $filters_db ) && !empty( $filters_db ) ) {
		if( in_array( 'added_group_document' , $filters_db ) && in_array( 'edited_group_document' , $filters_db ) ) {
		} else {
			if( in_array( 'added_group_document' , $filters_db ) ) { ?>
			<option value="edited_group_document" <?php selected( $defult_activity_stream, 'edited_group_document'); ?>><?php printf(__('Show Group %s Edits', 'bp-group-documents'), $name); ?></option>
			<?php }
			if( in_array( 'edited_group_document' , $filters_db ) ) { ?>
			<option value="added_group_document" <?php selected( $defult_activity_stream, 'added_group_document'); ?>><?php printf(__('Show New Group %s', 'bp-group-documents'), $name); ?>
			</option>
			<?php }
		}
	} else { ?>
		<option value="added_group_document" <?php selected( $defult_activity_stream, 'added_group_document'); ?>><?php printf(__('Show New Group %s', 'bp-group-documents'), $name); ?>
		</option>
		<option value="edited_group_document" <?php selected( $defult_activity_stream, 'edited_group_document'); ?>><?php printf(__('Show Group %s Edits', 'bp-group-documents'), $name); ?></option>
	<?php }
}
