‘Widgets’ are a simple and efficient way of adding content and features to the sidebars, or any other widgetized areas of your site. Many themes include widgetized areas in the header, the footer and even select places in the body of a site.
To manage the widgets available on your site, click the ‘Widgets’ link under the ‘Appearance’ tab in the WordPress dashboard. On the left you will see a list of ‘Available Widgets’. This is a list of all the widgets on your site currently available for use. On the right you are given a list of all of the available widgetized areas on your site.
To add a widget, drag-and-drop one of the widgets from under the ‘Available Widgets’ into the widgetized area you would like the widget to display in. Arrange the widgets by dragging them into the order you want them to display.
Clicking on the widget will reveal settings options for that widget. Once you have configured the widget, click ‘Save’ to publish the changes, click close to undo the changes or click delete to remove the widget from the widgetized area. If you want to disable a widget without losing its current configuration settings, drag the widget below ‘Inactive Widgets’ and the widget will be saved with all of its current settings for future use
Clicking the ‘Screen Options’ tab near the top of the WordPress dashboard will allow you to enable the ‘Accessibility Mode’ adjusting the way you interact with the widgets editor. For the option to manage or edit widgets and various other features in your theme from a visual editor visit the ‘Customize’ screen.
