Bootstrap导航栏搜索按钮

Question

我正尝试以下列方式在导航栏上实现搜索菜单。 有两种设计，即一个前屏幕＆lt; 767px，另一个高于767px。

基本上，我可以展开搜索栏，但展开的搜索栏的位置无法正确显示。

$(function(){
   $("#search-button, #search-icon").click(function(e){
     e.preventDefault();
     $("#search-button, #search-form").toggle();
   });
 })

#search-form { display: none; }

我会尝试这个;它遵循将表单添加到navbar的引导程序默认值，然后您可以使用CSS为移动视口调整它。

$(function() {
  $("#search-button, #search-icon").click(function(e) {
    e.preventDefault();
    $("#search-button, #search-form").toggle();
  });
});

#search-form {
  display: none;
}
@media (max-width: 767px) {
  .custom-navbar {
    text-align: right;
  }
  .custom-navbar #search-button {
    float: none;
    border: none;
    right: 0;
    text-align: right;
  }
}
