Menu ID empty

Hi Shishir,

great plugin!
I ran into following issue by adding a new menu item (via Admin Menu Editor):

PHP Notice: WP_Admin_Bar::add_node was called incorrectly. The menu ID should not be empty.

Could you have a look at w2o-admin-drop-down-menu/core/core.php:

line 22: // 0 = name, 1 = capability, 2 = file, 3 = class, 4 = id, 5 = icon src

line 54: $org_id = trim($item[5]);
line 55: $id = isset($item[5]) && ! empty($item[5]) ? ‘w2oadm_’ . $item[5] : ”;

The index for $id should be 4, right? At least this has fixed the issue.

Thanks
Jasmin
