Joomla Template Flex - Menu Designe

Hi, I am looking for a solution for the menu design. All submenu entries should appear at once when I move the mouse over the main menu item.

Can someone tell me which parameter I have to set at which position?
This works with another template, but not with the Flex template.
With Flex only the first submenu level is shown to me, but not the second level.
Can anyone help me there? Author Aplikko doesn’t answer since some days.
Kind regards

You may need some custom modifications for the item. It’s better to wait for an answer from the author ( they may provide free support ) or if you’re interested in paid support, you can contact me via this link

I have found it.

Kind regards
