I'm a UX intern working for a startup and i'm building an analytics platform that offers analytics driven marketing.
The current flow essentially moves the user through analytics from high level to granular, and in the granular views offers a CTA to access the marketing content and the associated lead lists they can send those marketing materials to.
I'm struggling to find the best way to offer those downloads. My PM thinks we should implement a 2 column modal that shows a preview of the marketing materials in 1 column and then 2 buttons that lead to the campaign and lead list in the 2nd column.
To me, this seems like an overly complex use of a modal and so I've been trying to push for a breakout page that essentially does the same thing. I've also made the decision to kill the side-bar navigation on this page for error prevention and include 2 links back to the previous page (<- back button at top of page and "return to dashboard" link at bottom of the page below content. My PM was strongly against killing navigation on this page which i kind of understand as his reasoning is that users could get "trapped" on this page.
In my google research so far, I have not found any good examples of a use case like this and so i'm kind of just designing off of my limited knowledge, mentor feedback, and PM directives.
If anyone has sense of best practice here I would really appreciate resources or additional guidance.
