After you add your new FAQ Widget to your page, you're probably going to want to adjust the shape and size of your Widget. Use the different options in the window to select the height and width of your plugin. We don't recommend it, but you can insert a scrollbar, title or border to your FAQ Widget. You’ll have more editing controls directly through the plugin.
