When Module ID for first Menu item Not clickable

I am using Menu behaviour: "On click"
And in first item Menu: [modid=616]
its showing the content from module id 616 which is custom module
its not clickable!!!! so that it shows the dropdown other links.

Its showing in console error:

Type Issue:
'null' is not an object (evaluating ('clicktarget.addEvent')
which is direct to the moomaximenuck.js in line:

clicktarget.addEvent('click',function() {

Is not possible to show the content of a moduleid in the first item menu and show the dropdown menu? and if yes maybe this is a bug?
thank you

Hi
if you want to show a module into a submenu on the first item, you must create a link and then a submenu which load the module :
- ITEM 1
-- Submenu which load the module 616
