So, if you add the module with forRoot() in your root module it's working, but not in your child module. Right?

Is your problem related to this issue #94?

PS: try to add more details to explain your situation

Also, did you check the official live example? https://stackblitz.com/edit/angular-modal-gallery-v7

Yes, i add the module without forRoot() in child moule,
i do a test in stackblitz, https://stackblitz.com/edit/angular-axdjwp
you can see this issue in this test

What? forRoot in child module is wrong. This is a common pattern in Angular. Forroot() is only for the root module.
In your example I don't see any forRoot(). You aren't importing the module in your root module.

Please check my example carefully, because it's working and you can copy the configuration. It's also explained in the official documentation website.

you are right ,if i add the module with forRoot() in my child module,it works
