Thank you for RC2!
I've found another CSS problem in RC2…
for modernbricksmenu in some themes. (zetagenesis, blueday,...)
instad of
@+
Z
…each tab with a false reveal ID so they could display even if having no content.
<div id="tab02" style="display:none;">{the second Mytabs is included here}</div>
if a tab does not have a link and does not have content then it is not showed.
