Need to have a left navigation XSL rendering created that will render current item in left nav as well as any child items that are located under current item.
Each item in the tree has the following fields
Show in Left Nav(checkbox, checked means show and not checked means do not show in left nav)
Left Nav Title(Single line text field that is the text that should be used instead of the item name in the content tree, if no name is given the content tree name should be used)
Content Tree Example
So say the user is on the About Us page the left navigation would look like the below
I have attached an example of how the XSL should be provided.
If you cannot demo the working XSL please do not bid on this task.
You must create the XSL in the sitecore context, meaning regular XSLT will not work, if you are not familiar with using XSLT & Sitecore please do not bid.
