Newsflash Wide Menu
We will send you the screenshots on how we have set it up so you will be able to refer to this.
First, News is set to Wide type https://www.screencast.com/t/j7sOGpwd72B and has the custom widget area chosen. Then the Categories custom link is added as sub menu to News https://www.screencast.com/t/m6CPISbb(don't link, don't show) and the News custom widget area is chosen .
Here is for the Future link https://www.screencast.com/t/SApcnEI7
and the same procedure you will have for the likewise menu items.
Off course you will have to add the widgets to the widget area if you are somehow missing them.
Hope you will manage with this guidance and if you still encounter an issue customizing this please provide us with your wp-admin credentials so we can help you with this.
