When the browser window is windowed (or fairly small) the SideNav shows and hides based on activation via a button, this works well. However, when the browser window is maximised the SideNav permanently appears on the left of the screen, this would be Ok except that the left part of the workable area of the browser window is hidden under the SideNav. If the SideNav becomes permanent then the workable area of the screen should shrink so that it starts on the right-hand edge of the SideNav not under it.

Could someone please look into this issue.

Thank you.
