Select the Insert menu and then select More Gadgets.
Find and open the Insert menu in the Google Sites Editor. You should see a list of available components and gadgets you can add to your site, like Images, Links, and Tables. Find and select the More Gadgets option. This allows you to install customizable tools such as the POWr Contact Form to your site.
The Gadget manager will be visible. Choose Add Gadget by URL. Then add this exact URL into the field. Choose Add to complete.
Now that you've added your new, editable Contact Form Widget to your Google Sites page, you might want to resize the Widget. Use the options in the pop-up to choose a height and width for your plugin. You can decide to create a title, scrollbar or title around your Contact Form Widget, but we advise against it. You will have more editing options through the plugin.
Set up POWr Contact Form
Visit your live Google Sites website and select the gear icon in the upper right corner of your Contact Form Widget.
In the POWr Editor, click Import Existing Contact Form, find Contact Form- and click Copy.
