[richfaces-issues] [JBoss JIRA] Commented: (RF-6730) rich:contextMenu shows in wrong position when used inside scroll div
[

Alex Peelman commented on RF-6730:
----------------------------------
In some cases, when the scrollbar is long and scrolled all the way to the bottom, the pop
up just disappears from the screen.
After fiddling around with firebug I noticed that the top (css element) position of the
generated context menu is bigger than my actual document height.
I suggest the following solution :
1) check if the context menu its top + height > document.height
2) subtract the difference from the top and use this as starting position
var correction = element_top + element_height - document.height
if ( correction > 0 ) {
// shift the element at least <correction> pixels up
element.style.top = top - correction;
}

Environment: FF3, Ubuntu 8.04, JSF 1.2, JBOSS Seam 2., JBOSS 4.2.3

I have a lot of context menu's placed inside a scrollable div. When the scrollbar is
at the top the pop up shows correctly but when I scroll down the pop up moves more towards
the bottom.
The context menu is created as followed
<rich:contextMenu attached="false"
disableDefaultMenu="false"
styleClass="left"
id="contextMenu"
style="z-index:1500"
> ...
And is summoned by a rich:componentControl onclick event
<h:panelGrid columns="2">
<h:outputText value="Actions" styleClass="actions" />
<h:graphicImage value="#{root}/img/arrow_down.png" />
<rich:componentControl event="onclick" for="contextMenu"
operation="show"></rich:componentControl>
</h:panelGrid>
I will attach pictures which shows the problem
