CMS Create a links list in Sidebar in CMS for one section only?
 

Hi guys,

I would like a widget in the CMS sidebar to only show up in a certain Section and then allow me to display some links. What I am trying to do is that I have a section named Books where I will be adding articles from three separate books. I would like a sidebar widget where I am able to organize the articles under the individual book that they belong to.

So a linked list with something like this:

-Book A
--Article 1
--Article 2
-Book B
--Article 3
--Article 4
-Book C
--Article 5
--Article 6
--Article 7

With each article being linkable in that list.

Is something like this possible?
