Is there a way to get the submenu to render at the time of menu initialization? At the moment, it appears that the submenu is not initialized until it has been accessed the first time by the user.
FYI for anyone who may come across this. Worked great.
Response from support:
Can you please clarify the use-case? If I understood you correctly,
topmenu.getMenu(-1); //non existing id
will force the rendering of the submenus for the topmenu. Please check the following snippet:
