[support] How to Create this complex page?

Hi Group, I'm wondering if someone can get me started on what set of modules to start with to construct a page like this: I'd like the following elements on one page/view: 1. A Select List of node titles based on a taxonomy term: 2. Once a node title is selected, the corresponding node teaser is displayed under the select list, via Ajax? If possible, I don't want the page to refresh. 3. I'd like 3-4 select lists of node titles based a different taxonomy term, all on the same page with the same functionality as #2. Possible without a custom module? Thank you, Lynn
