Hide panel-header of a element in a dashboard with multiple elements

Hi!

I am using PHPRunner 10.4 (build 36834).

I have a dashboard with multiple elements that display reports and charts. I would like to hide the panel-header of one of the elements (chart).

I tried with the following code on the Javascriptonload event in the Chart Page, but didn't work.

$("ul[class='panel panel-heading']").hide();


Following CSS code works, but it hides the header of all the elements

.panel-heading{
display:none;
}


Any direction appreciated.


Thank you,

Abhi
