Webform Submit Button allows a webform creator to position the submit button inside a webform. By default webform submit buttons are placed at the bottom of a webform and cannot be moved.
Webform Submit Button is installed in the usual way. See [Installing modules (Drupal 7)] (https://drupal.org/documentation/install/modules-themes/modules-7).
This module creates a new webform component called submit_button. The component can be placed in the webform like any other webform. It has no meaningful settings on it's own. It becomes a placeholder for the real submit button that is generated by webforms. On hook_form_alter the placeholder is removed and replaced by the webform submit button.
