I'd like to modify the context menu for a right click on a specific item (a tr) to display some custom navigation options instead of the standard content. So far, I've found two ways of doing this: either bind some new behavior to the contextmenu event, and create a new div/dropdown menu based on the location of the event, (i.e. create my own context menu from scratch), or else use a plugin like this jQuery plugin that will do the exact same thing for me.
What I'm wondering is if there is a way to use the skeleton of the default context menu, and just add some <a>s or divs that are bound to the events I want to trigger in place of what's already there. Is there a way of modifying the existing context menu, rather than dumping it and building my own either from scratch or with a plugin?
