BuddyPress.org

up,

no idea?

I found a workaround, I’am quite not completely satisfied but…

First of all, disable members list on group:

function change_access_group_nav_tabs() {
  if(bp_is_group()) {
    buddypress()->groups->nav->edit_nav( array( 'user_has_access' => false ), 'members', bp_current_item() );
  }
}
add_action( 'bp_actions', 'change_access_group_nav_tabs' );

(btw, setting the value to true actually make the the nav items always here, but we still can’t access the group list on click)

And then I simply add a custom BP Group Extension to make my own members list:

class Group_Extension_List_Members extends BP_Group_Extension {
    /**
     * Here you can see more customization of the config options
     */
    function __construct() {
      $args = array(
          'slug' => 'members-list',
          'name' => 'Membres',
          'access' => array( 'anyone'),
          'show_tab' => array( 'anyone'),
          'nav_item_position' => 12,
          'screens' => array(
              'create' => array(
                  'enabled' => false
              ),
              'edit' => array(
                    'enabled' => false
              ),
          )
      );
      parent::init( $args );
    }
    function display( $group_id = NULL ) {
      //Remove user who do not belong to the group on members loop
      function filter_for_groups( $members_template_has_members, $members_template, $r ) {
        for ($i=sizeof($members_template->members)-1; $i >= 0 ; $i--) {
          $user_id = $members_template->members[$i]->id;
          if(!groups_is_user_member( $user_id, bp_get_group_id() )){
            $members_template->member_count = $members_template->member_count-1;
            array_splice($members_template->members, $i, 1);
          }
        }
        if ($members_template->member_count <= 0) {
          return '';
        } else {
          return $members_template_has_members;
        }
      };
      add_filter( 'bp_has_members', 'filter_for_groups', 10, 3 );

      require('/Your/theme/custom/members/loop/members-loop.php');
    }
}
bp_register_group_extension( 'Group_Extension_List_Members' );

Hope it will help other in the future, And I’m still open to know the good way to proceed.
