Cet article présente un exemple d'utilisation combinée de select et suggest, prenant en charge la sélection directe dans la liste déroulante et le filtrage des entrées dans le contenu de la liste déroulante.
L'effet global est le suivant :

1. Tout d'abord, vous devez importer les fichiers suivants

<link href="select2.min.css" rel="stylesheet" /> 
<script type="text/javascript" src="jquery-2.1.4.min.js"></script> 
<script type="text/javascript" src="select2.min.js"></script> 
Copier après la connexion

Il convient de noter ici que jquery doit être placé devant select2.
2. Quelques exemples

<!DOCTYPE html> 
<html lang="en"> 
 
<head> 
  <meta charset="UTF-8"> 
  <title>Document</title> 
  <link href="select2.min.css" rel="stylesheet" /> 
  <style type="text/css"> 
  .select2-dropdown { 
    margin-left: 8px !important; 
    margin-top: 20px !important; 
  } 
  </style> 
</head>
