Angular, React, HTML, Vue, Laravel versions have different sets of functionality. Your mentioned page is implemented only in the Metronic HTML version.
But you can use the same HTML+CSS structure and inject it into your Angular code, it will look the same as in the HTML version, cause all SASS files from the HTML version are imported in the Angular version also.
