Choose Insert, and then More Gadgets.
In the Google Sites Editor, open the Insert menu. You will see a list of components you can embed on your site, like Tables, Images, and Links. Find and select the More Gadgets option. This will let you add editable tools like POWr Order Form to your site.
Paste in URL
You will see the Gadget manager. Select Add Gadget by URL. Then add this exact URL into the field. Click on Add to finish.
Change Height and Width
Now that you have embedded your new, fully customizable Order Form Widget onto your website, you'll probably want to change the shape and size of the Widget. Using the options in the pop-up, pick a height and width for your plugin. You can decide to create a title, scrollbar or title around your Order Form Widget, but we advise against it. There is more editing control through the plugin itself.
Set up POWr Order Form
Go to the live Google Sites website and click the settings gear in the top right corner of the Order Form Widget.
In the POWr Editor, click Import Existing Order Form, find Order Form- and click Copy.
