I am trying to create an option in the right-click menu that is dynamic based on the user's action. If the user selects some text, then right-clicks, the option will say "Display It". If the user right-clicks without selecting some text, the option will say "Select Some Text First" and be grayed out. I am wondering how do I achieve this? I currently have it so that the option will appear only when the user has selected some text. I am unsure how to modify it to meet my second requirements. chrome.contextMenus.create ({ title:"Display It!", contexts:["selection"], onclick:function(info,tab) { chrome.tabs.sendRequest( tab.id, {callFunction: "displaySidebar", info: info}, function(response) {console.log(response);} ); } });
