css accordéon défiler vers le haut de la page avec le panneau actif

Question

J'utilise un menu Accordéon CSS sans JS. Mais j'ai un problème. Lorsque j'ouvre le sous-menu, la page complète de mon site Web défile automatiquement jusqu'à ce bouton Menu avec le sous-menu sur lequel je clique et qui n'est pas corrigé. Je veux juste que le sous-menu s'ouvre sans faire défiler ma page. Theres an Solution?

Answer 1

Le saut se produit en raison de href="#id"

vous avez deux options modifier le code pour ne pas exiger href="#id"

ou

ajouter cette

$('.accordion a').click(function (e) { 
    var x = window.pageXOffset, 
     y = window.pageYOffset; 
    $(window).one('scroll', function() { 
     window.scrollTo(x, y); 
    }) 
}); 

Où puis-je ajouter cela? par @pphil23

entre <script></script> avant </body> ou

<script src="js/file/path"></script> en tant que fichier externe avant </body>
