To add these Widgets to your sidebar, you will click on the widget and select “Sidebar” from the dropdown menu. Once you have selected “Sidebar”, click “Add Widget.”
Alternatively, you may drag and drop the widget into the area you wish it to be placed.
Adding a Video using the Text Widget
After you have added the Text widget to your sidebar, it will populate on the left side of the screen.
When you click on the widget, it will expand to show a title and description box.
Enter your desired title for the video you would like to add then embed the iFrame code in the description box, as shown in the screenshot below.
Once you have entered this information, click “Save.”
Adding a YouTube Channel to Your Sidebar
After you have added the “YouTube Channel” widget to your sidebar, it will populate on the left side of the screen.
When you click on the widget, it will expand to show a Title box and YouTube user or channel box.
In the YouTube user or channel box, you will paste the username (not a URL or embed code) of the YouTube Channel you would like to add.
Then enter the desired title for this channel that will be reflected on your blog and click Save.
