The Page template is provided with a sidebar that you can place on the left and right side of the web page. A sidebar in WordPress refers to a widget-ready area used by the website to display information that is not part of the main content but is displayed in a vertical column.
In your left sidebar navigate to Appearance > Widgets and locate the Page Sidebar box as displayed in the image below.
As you will notice, there are Available Widgets displayed in the left part of the page. On the right side, you can find the Page Sidebar where you will need to drag and drop the widgets that you want to display on the page.
Airent has 13 custom widgets available to customize your sidebars. To place them in the sidebar, just click on it and select the destination sidebar and click on Add Widget.
