Importing tabs from other files

I’ve successfully started using dcc.tabs for simple apps, but I’ve reached a point where my content is so large it doesn’t fit neatly into a single file. It’s necessary to keep the tab’s content in separate files and import the data, as suggested by @chriddyp in the dcc.tabs documentation, here .

Can anyone share a successful example of how this is done? I’ve tried to imitate the example provided by @GwendalD here but I’m doing something wrong. I’d benefit from seeing how others solved this problem – the simpler, the better! Thanks.

(FWIW, I did not find the example about URLs and Multi-Page App Tutorial entirely helpful, as it doesn’t incorporate dynamic content called back within dcc.tabs Method #1).
