Looking for example multi-panel (tabbed) project with multiple templates (one for each panel)

I’m finishing off an application and it would be great to use templates to get fine grain control over the layout of charts and widgets.

My application is multi-tabbed (multi-panel) with charts and widgets on each tab. The chart types are different on each tab. I’d like to layout the tabs better, so I want to go to Jinja2 templates. My understanding is, I need a Jinja2 template for each tab of my application.

It would be a lot easier for me to follow what someone else has done, so I’d love to see a multi-tabbed application that uses multiple Jinja2 templates. Is anyone aware of applications with source code I could look at? Thanks.
