Widgets are tiny blocks of specific functionality that you can place in your WordPress sidebars (also known as widget-ready-areas). For beginners, this is an easy way to add things like quotes, popular posts, Facebook Like Boxes, and other dynamic items on their WordPress site. Widgets allow you to add different functionality and features to your WordPress sidebars without writing any code.
Widgets can be found on Appearance -> Widgets page in your WordPress admin area.The big panel on the left side shows all available widgets. The small panels on the right are the widgetized areas.
How to add a Widget
There are multiple ways to add widgets to sidebars available in your WordPress theme. The easiest one is to simply drag and drop them to your sidebar. You can also click on a widget title from the list of available widget. WordPress will show you the list of sidebars where you can add this widget.
How to remove the widget
Look for the widget that you want to remove in your sidebars and click on the widget title to expand it.Below the widget settings, you will find the link to delete the widget. Deleting a widget will remove it from your sidebar and will also delete widget settings like title or any options that you selected. Also you can drag the widget back to the left panel to delete a widget from sidebar.
Some widgets are too simple and don’t have many options in their settings while others have many options and settings.If you want to keep the widget setting for future use, drag it to the Inactive Widgets instead of the Inactive Widgets panel.
