JavaScript, DOM et API Web HTML5

Bonjour à tous,

voila j'ai fait quelques recherche sur alsacréation pour styler la balise select. J'ai vue que c'était impossible via le CSS. J'ai donc trouvé un petit script Jquery sur le net très sympa qui me donne l'effet que je souhaite mais j'ai un petit souci ....

J'ai un page avec un formulaire d'inscription vers le bas de page il y a mes balises de type <select></select> le problème est que quand j'arrive sur la page au lien d'être tout en haut ma page est tout en bas comme si j'avais fait un scroll j'ai essayer de regarder dans le fichier JS mais je trouve pas de quoi ça peut venir.

Le problème est présent que quand le script et sur la page

Voila le code source :
