That is an async loaded mega menu. There is nothing like it out of the box in APEX but the APEX menu widget can be customized.
The menu widget does support async (https://docs.oracle.com/en/database/oracle/application-express/18.2/aexjs/menu.html#asyncFetchMenu ) but I don't think there are any examples of this out there. APEX builder or components use it in a few places.
The menu widget supports custom content for mega menus (https://docs.oracle.com/en/database/oracle/application-express/18.2/aexjs/menu.html#customContent ). I show an example of this here: APEX Media List Mega Menu – HardLikeSoftware
I don't know if custom content and async can be used together. Perhaps you don't care so much about the async part. The rest of that example is just markup and css.
Thanks for your reply John Snyders.let me check the above link.
