Thank you Sir.

But there are no examples of how to have links to other sites on each menu, based on the id of each row of data. Anyone can help?

Code updated at gist to use rowid and cell data.

More explanation: if you want to open link on clicking certain menu.

If you click on (for e.g.) bravo, it would return its key there in callback.

Now there you can put if check and do window.open() e.g. see line 64
https://gist.github.com/gridphp/b5416f203fdac93623b614a5f455731c#file-phpgrid-context-menu-php-L64

var m = “Row:”+ row +”, Gender:”+gender+”, Clicked:” + key;
if (key == ‘fold2-key2’)
window.open(‘billing.php?param=’+gender);
