Most WordPress widgets can be embedded in Oxygen from +Add > WordPress > Widgets.
For most widgets, the widget settings will appear in the Basic Styles tab.
After editing the widget settings, click Apply at the bottom of the panel to save the settings.
Some widgets have elaborate and complex JavaScript settings screens that are not fully compatible with Oxygen's interface. These widgets must be edited in the WordPress admin panel.
To add these widgets to your pages, follow these steps:
Install the plugin WooSidebars.
Create a widget area from Appearance -> Widget Areas.
Go to Appearance -> Widgets and add the widget to your newly created widget area.
Embed the widget area in Oxygen from Add+ -> WordPress -> Sidebars.
