Thank you. The question was a bit ambiguous.
I want to know whether the Appery.io visual IDE can separate an app project back into individual HTML source files when the multi-page setting is disabled (after enabled) and recombine into a single HTML source file, start page, if enabled?
Can you switch back and forth between a multi-page template and separate source html pages automatically by changing the multi-page setting?
If the multi-page setting is a permanent change, and after selecting it you cannot go back to separate source HTML page files, the option should probably not be (uncheckable) in settings.
I have not be able to return to separate HTML source files after enabling the multi-page template.
