title: Sitecore create drop-down button in RTE populated from master database
body: <p>I'm trying to create a drop-down button for the rich text editor (RTE) in Sitecore but cannot figure out how to implement this.  I would like something similar to the 'Insert Snippet' command shown below, but with the source of the dropdown driven by content from the master database instead of core items within the html editor profile.

  <p>The closest approach I've found is this <a href="http://www.markstiles.net/Blog/2012/02/17/adding-button-to-rich-text-editor-in-sitecore-6-4.aspx" rel="nofollow noreferrer">article which describes how to add a button which opens a dialog in the RTE</a>.</p>
  
  <p>Another option could be to have a save handler which can create the snippet items in the core database based when items are created/edited in a certain area of the master database.</p>
