In the image below you can see that I have added some additional HTML to the TopContent of the Person Summary screen.
The following code can be added to the custom content box of a system screen like the PersonBoxLong or CompanyBoxLong.
[code language="javascript"]
<script>
crm.ready(function () {
var myOutPut = "<table border=0><tbody><tr><td class='TOPSUBHEADING'><UL><LI>This is anything I like. </LI><LI> It will appear on the right handside of the TopContent area</LI></UL></td></tr></tbody></table>";
var x = $("#EWARE_TOP").children();
var y = $(x).children();
var z = $(y).children();
var a = $(z).children("td:last");
a.after(myOutPut);
})
</script>
[/code]
It will add the defined output HTML to the right hand side of the existing TopContent and it will do so whether or not someone has already added fields using the TopContentBox screen e.g.PersTopContent.
