2016-03-04 We've added a new integration method: lightbox integration: it's a mixture of simple and advanced integrations and it's now the default in all the widgets generated in the quick setup. The lightbox integration shows the reservation form (or other content, such as search results etc.) in a lightbox (overlay) on the same page as the widget. It works great with all widgets, such as the reserve button, calendar preview, search form price preview etc. The lightbox integration is not a 100% advanced integration because it uses an iframe in the lightbox. However, your templates will still be applied, just as with 'simple integration with templates'.
