This is a normal Joomla article, with the FlexiContact Plus plugin included in a div, floated to the right. The plugin has exactly the same features as the main component, with all the same optional fields, captchas, and multiple configurations. We just chose to show a very small example here.
FlexiContactPlus uses Ajax to validate the form data, which means that it doesn't need to re-draw the page when the user clicks the send button. It communicates with the server "behind the scenes", re-drawing only the parts of the page that it needs to change.
