Warp comes with a sophisticated layout system to create any kind of sidebar or widget layout. You can easily manage the sidebar's positions and widths in the theme administration. Widgets can have different styles and be placed in any position offered by this theme. Each position has its own layout. You can align widgets side-by-side, stack them or choose your own grid layout. Show or hide widgets on mobile devices, while the grid adapts perfectly to your layout.
There are other module positions which come in handy, namely:
off-canvas - Appears on the left to show the mobile menu. It can also be used to place other modules
modal-c - shows a module in a popup dialog box. See this page for more information
mega-menu - You can use this position to add a third-party menu
