Show dialogs/windows as "overlay" (like in options)?

[Vano]

Hello.

I'm trying figure out how options tab shows other dialogs as "overlay" of some sort (visually only, not the traditional xul overlay) instead of popups as separate window. It uses the same .xul files that otherwise would be independent windows, but the style is all different.

For example I'm trying show chrome://global/content/commonDialog.xul inside of my own .xul file

Any suggestions?

Thanks.

Do you mean inline options? https://developer.mozilla.org/en-US/Add ... ne_Options

No, I mean browser's options. For example about:preferences#security click on "Saved logins" that opens a .xul that looks like an "overlay" of options page.

It is here, plus appropriate styling, basically just a box with a browser in it:
