Megamenu disapear when changing existing content to code

www.svv04.nl/web2022/index.php/logisticsLook to this link and see what happend, i have only change the content of the logistic and when i refresh you wil see the megamenu is changing in an whole black item and the memgamenu is no working anymore.I can only enter code using jce editor, others don't work. Do you have an solution fot this or what do i wrong, You may have an superuser account but i don't know of this here is safethe first attachement is the problem, the second is which content i need. and the mega menu must be intact.

Hello,

The problem is in the content you added, not in the template. The mega menu works on all the pages except the Logistics page. This probably means that you copy/paste the incorrect code on the page that contains some elements that are blocking the execution of Javascript on the page.

From the W3C checker, I see this page has some unclosed divs: validator.w3.org/nu/?doc=https%3A%2F%2Fw...ndex.php%2Flogistics

Please correct this. It's not recommended to copy/paste from software such as MS Word or Excel directly to the Joomla editor.

Hello Milan, Thank you for your quick answer, In Joomla 3 no problem with the menu, Exacly the same code used, I will try your suggest this week before i will continue developing. this is an important part. These data come from the football association this are not self-completed tables from word or excel

Hello,

The error on this page probably existed in Joomla 3, but maybe it didn't break the whole page layout. From the W3C validator, it's clear that your page content has problems with unclosed DIVs. I don't know where the content for this page is coming from, but your should try to find and fix this.

I think it is solved The problem seems the jquery invoke.
Thank you for your help
