Widgets are the ones that make it easy for WordPress beginners to display anything into the sidebar of their blog. There are also several WP plugins that extend the functionality of the widgets in WordPress. Widgets usually allow titles which help in identifying them as well they’re displayed with the same name in your blog. However, these titles may look clumsy in few situations where you’re adding Feeds or Search box codes as these codes already come with a default title and two titles will make it look odd.
You can anyhow make use of the ‘Remove Widget Title’ plugin and prevent the widget titles from being displayed on your blog.
After installed and activated, go to Appearance > Widgets. Open the widget in which you want to hide the title and simply add an exclamation mark (!) before the title. This will disable the title on your widgets while viewing the live site.
