I'm planning on adding a side navigation bar to my DNN site. There will be 2 sections to the nav bar. When an author adds a new page, I'd like to present them with a drop down list to specify which of the two areas of the side nav bar to display the link in that links to the page they're creating.

So, I need to add controls to an existing DNN page (the page creation tool), modify the sql statement that runs when the user adds the page, and add a new column or table to capture the new page data.

Is there a framework for these kinds of extensions or should I just alter the pages/db schema as needed?

Tks.

Yeah, it's the "make sure you can still upgrade DNN" part I'm worrkied about.

Is there a generic table in the db I can use to create new field/value pairs? If not, what's the recommended way of extending DNN's data storage features?
