Interactive Decision Tree

I need an interactive decision tree, aka troubleshooter, that will leave behind up-to-date bread crumbs of each selection along the way so that you can clearly see the path taken. The bread crumbs should be left in a text box so the user can select and copy to a work log. Ideally it will also have a "Copy" button which selects all and copies with a single click. Example: User chooses troubleshooting bucket > User is presented with options > Depending on selection user is presented with more options > Continue until resolution is met (ie: Audio > One way audio > End user cannot hear person on the other end > Issue persists while using speakerphone and headset > Master reset performed > Issue Resolved) It thinks for the user and walks them through a logical troubleshooting process once the appropriate content is added; assuming they choose the correct options along the way. Requirements: -Interactive Decision Tree -Back-end that allows admin to easily, quickly and efficiently add the content for the trees (there will be many) -Will need to be able to add links and possibly images to the content -Copy friendly, up-to-date bread crumbs with one click select all/copy button for memos -Back button - back one step -Main/Home button - return to all buckets of troubleshooting options -Needs to be as efficient as possible under load, hundreds of users clicking throughout the day -Aesthetically pleasing, professional I am not trying to re-invent the wheel but I need something to fit my needs exactly as I see them. If you know of an open source code that you can use to customize to my needs I do not mind at all. I can show you an example of something I have started and you can feel free to use it if you choose.
