Thank you Dimitar,
The first, I am very impressed with your support – very responsive and efficient.
The solution is a good and working for the regular menu.
This line
$(“.jqx-menu-popup”).append(‘<iframe class=”cover” src=”about:blank”></iframe>’);
must be placed after every menu source change.
Regarding using jQWidgets context menu on Google Earth plugin it seems the same solution cannon be implemented?
I attached the sample html file for context menu:
