Currently, the subgroups tab cannot be assigned as the default group tab, but you can use the following function code to implement such a configuration. Please see the steps below:

Note: Make sure to have a complete site backup before proceeding

    1. Go to Appearance - Theme Editor.

    2. Under Select theme to edit, choose (BuddyBoss Child/whatever theme is active), then click Select.

    3. Below Theme Files, select Theme Functions (functions.php).

    4. Append the code just before the closing PHP tag “?>”:

add_filter( 'bp_groups_default_extension','bb_custom_sub_group_tab');
function bb_custom_sub_group_tab( $default_tab ){

  $group = groups_get_current_group();//get the current group

  if( empty( $group ) ) {
    return $default_tab;  
  }

  // Check whether the group has sub-groups, in that case enable the subgroups tab.
  if ( bp_enable_group_hierarchies() ) {
    $descendant_groups = bp_get_descendent_groups( bp_get_current_group_id(), bp_loggedin_user_id() );
    if ( count( $descendant_groups ) > 0 ) {
      return 'subgroups';
    }
  }

  return $default_tab;
}

    5. Click Update File to save the changes.
