Javascript-interface for repeat elements function

Adding new blank answer requires page-reloading. It's not comfortable. Using advanced opportunities of YUI library we can realize adding blank choices without it. Button "Blanks for 3 more Choices" will be changed to "Add blank choise".http://imglink.ru/pictures/21-09-10/f85258328f02d65164e6a15644e5d8a9.jpg

Pushing button Add blank choise will add one empty answer to the page without reloading.

Another addition is removing answers from page withou reloading. Removing answer will be able, if all text fields(input text or textarea) are empty.
