Hello,
I have made a test for the container property of TWebMainMenu component:
I put a Webpanel1 aligned at Top, and set webpanel1 as the Twebmainmenu's container and it works. And displaying of mainmenu is fine(see below picture).

Lower part of the mainmenu was covered, thus menu cannot be displayed completely.
For your reference, here is the test file : 61. mainmenu.zip (1.4 MB)
Thanks,
