I reviewed your ticket. What you are trying to achieve is really hard because it is possible trough Sitefinity and at the same time you can`t take that road and look for other alternative.
Please consider we are not fully aware with the exact requirements of your client. News items are to be shown trough the news widget and the navigation is designed to show pages.
With the built in navigation widget you can create Tree navigation and set "allow collapsing to true" and "Show all levels expanded initially to false ". Note when you click to some page of the expanded node the node will not persist your other expanded nodes like they were on the previous page ( it will appear all collapsed or all expanded). To achieve the persisting of expanded nodes you will need to create a custom navigation widget and maybe TreeView
will be suitable, you may review other menu types in the link. The color and desired behavior can be set using CSS, you can try using our Visual Style Builder
to create a skin for TreeView that suits your demands. I have attached a sample TreeView control you might find interesting ( it is persisting your changes ( expansions ) ).
Hope you find a resolution to the limitation problem. If you have further questions write back.
