title: Chrome extension context menu with custom context
body: <p>I created a context menu in my chome extension as a checkbox, I am successfull to create the menu which will be visible only for editable field. </p>
  
  <p>The problem is I need to display menu as checked, according to a data attribute in the textfield(focused element). With the following code, it is displaying checked in a global level(means if i checked the menu in one page/elemebt is will remains checked for other page/elements as well.)</p>
  
  <p>How can I make it checked/unchecked according to the element's data attribute ?</p>
  
  <pre><code>var addinMenu = chrome.contextMenus.create({

      "type": "checkbox",
      "title": "Disable",
      "parentId": addinMenu,
      "id": "myaddin_disable",
