The Sidebar often behaves differently on mobile display and differently on desktop display.
It has an effective feature that offers to set it in opened or closed state depending on the specified screen resolution.
This functionality can be achieved through mediaQuery
property that allows you to set the Sidebar in an expanded state
or collapsed state only in user-defined resolution.
window.matchMedia() method returns the object of parsed
media query
string. The value of matchMedia() can be any of the media features of CSS @media rule. For example, min-width and max-width.

public width: string = '280px';
public mediaQuery: object = window.matchMedia('(min-width: 600px)');
