How to work around no "layout: blank" option in Confluence modules (manifest.yml), like in Jira

Forge Forge UI Kit and Custom UI

Note: We’re using custom UI.

Jira’s page modules (e.g., https://developer.atlassian.com/platform/forge/manifest-reference/modules/jira-project-page/#properties) have a layout: blank option that removes a built-in header and allows the iframe to take up the whole panel.

However, in Confluence’s page modules (e.g., https://developer.atlassian.com/platform/forge/manifest-reference/modules/confluence-space-page/#properties), no such option exists.

Here’s the unhideable built-in header in Confluence:

The extra header is unnecessary… we just want to have our own header rather than have the less attractive built-in one.

And here’s what happens when we try to show a modal in the iframe:

It doesn’t take up the whole panel, so it doesn’t look like a real modal.

Has anyone found a workaround for this issue? Is there another manifest.yml setting I’m missing besides layout: blank in Confluence? Or another trick?

Hi,

At Capable, we’ve had to work around this in Confluence for quite some time.

The only way to control the entire viewport today is to embed your app inside a modal, which you can open when they click on the page. This isn’t ideal, and we’ve been advocating for a view where we can fully control the entire space in Confluence, but that capability isn’t available yet the same way it is in Jira - leaving us with two sub-optimal choices.

Your best bet is to chose from a max or the new fullscreen modal sizes which will let you control all available space.

Best of luck,

Jack
