@mikejhills We need to update the documentation page because this example is currently not available there. Here is a quick example:

<button
  type="button"
  class="btn btn-lg btn-danger"
  [mdbPopover]="template"
  mdbPopoverHeader="Popover title"
>
  Click to toggle popover
</button>

<ng-template #template>Popover template</ng-template>
