Forge Custom UI - full screen view

Hi All,

I am in the process of migrating an existing Connect Macro App, Visio Publisher for Confluence over to Forge.

In summary the Forge App uses custom UI to render HTML content stored as a page attachment. The screenshot below shows the Forge app WIP

The existing Connect app has a link that launches the embedded HTML content in a new browser window (not shown in the Forge screenshot).

I can see that the router offers similar functionality but requires a relative or absolute URL (that I don’t have - the page attachment source is written to the window body in the Connect version).

Optionally, I have seen that Modal might be used. However, I haven’t been able to find a worked example of its use.

Is there any other option? Ideally I would like the UX to be similar to that when a user clicks “view” on the attachments page i.e. takes the whole screen real estate.

Cheers,
Andrew
