select box - przycina za każdym razem podczas wczytywania Opcje

[Mateusz_M]

Witam, w wyszukiwarce umieściłem rozwijaną opcje przeszukiwanych zasobów strony. Problem w tym, że co przeładowywuje stronę to jest taki efekt:

Daj link do strony, bo to problem wyświetlania, nie teoryzowania na temat kodu.

[Mateusz_M]

Niestety nie mogę podać linka strona jeszcze nie jest publicznie dostępna. Może jakieś wskazówki co może być przyczyną? ewentualnie jakaś zasada jest jak obchodzić się w takiej syutacji.

[Rewil]

Strona działa bez JS'a?
Bo jeżeli nie, to możesz tego selecta ukryć CSS'em.

Jeżeli tak, to podmień może:

(function($){

na:

$(document).ready(function() {

lub ew. do tego ready, wczytuj funkcje które mają się dziać po załadowaniu strony.
