How to Customize the Sidebars
If you want to use a customized sidebar on your page, simply use the settings in Page Widgets panel in the page options. Here you should select Customize (is selected by default if you create new page) and then simply drag-and-drop any widgets of your choice from Available Widgets panel to the Sidebar panel. After setting up / populating your widgets don’t forget to click on "Save" at the bottom of each widget to save your widget settings for this customized sidebar! For detailed description of all available widgets see chapter "Widgets".
