This template lets you specify the HTML code which will be used for the reservation form embedded on your site. The special tags you can use here are:
$(reservation_form) - displays the reservation form (required).
$(your_rate_box) - you can move the price/error panel to any location using this tag (more here...)
$(your_rate_box_floating) - same as $(your_rate_box) but this version will float vertically and will always be visible as long as the booking form is scrolled into view. Note: the box will not float horizontally so make sure the initial horizontal position is correct.
$(your_rate_box_sticky), $(your_rate_box_sticky_right) - different versions of an always-visible 'your rate' box, in this case the box will always stick to the bottom of the browser page (first_tag) or to the right of the browser page (second tag and only on non-mobile devices)
$(reservation_steps) - (advanced integration only) shows reservation steps reflecting your current settings. The current step will be highlighted.

The template can also use general tags (how to use tags?). Please see the following FAQ questions for a detailed tag list:
