I don't know how to use angular material controls in my application

I have installed angular material

I have created Material Module

I have imported this module in app module

But in any template in which I insert a control I always get the same error of "is not a known element:"

For example, here I need a date picker

Any idea, please?

Thanks

>Solution :

You should avoid creating a dedicated material module for tree shaking.

But the issue is probably that you only imported the modules, and did not export them.

Try adding an exports array to your material module.
