Components

<exm-drawer>

It is basic component that probably should not be used directly. It serves only as drawer without form functionality, so it is content agnostic. You can pass any dom markup as children of this component.

<exm-form-drawer>

Wraps around exm-drawer.

Provides form functionality to drawer:

• submit and cancel buttons
• title
• material styling
