How to set the trigger only for the third column td,not all the td in a grid?
I had set all the td like this:
my.contextMenu({
trigger: '#Grid td ',
rightButton: true,
menu: '#testMenu',
callback: ctxCallback
});

Hi,

 
I would suggest to use the following jQuery selector to achieve the desired behavior:

$("#Grid tbody tr td:nth-child(3)")

Kind Regards,
