【问题描述】：
我在我的应用程序中使用algolia autocomplete。我想建立一个搜索栏，像page 上的可扩展示例一样扩展。我有一个带有标题栏的布局，其中包含更大屏幕的搜索输入。在小屏幕上，我只有一个放大镜图标，单击该图标会切换另一个带有搜索栏的标题，我最初将其隐藏。这是fiddle，我无法开始工作，但希望它仍然可以为您提供一些概述。这是布局：
<header class="mdc-toolbar mdc-toolbar--fixed toolbar--custom">
<div class="mdc-toolbar__row">
<section class="menu mdc-toolbar__section mdc-toolbar__section--align-start">
<a href="#" class="material-icons mdc-toolbar__menu-icon">menu</a>
<span class="mdc-toolbar__title">Title</span>
</section>
<section class="mdc-toolbar__section">
<form action="/search" method="get" class="search-field-desktop">
<div class="mdc-text-field mdc-text-field--box mdc-text-field--with-leading-icon autocomplete-search-field">
<i class="material-icons mdc-text-field__icon" tabindex="0">search</i>
<input name="q"
type="text"
class="mdc-text-field__input search-input-js aa-input-search"
placeholder="Search for players and videos ..."
aria-label="Full-Width Text Field">
</div>
</form>
</section>
<section class="mdc-toolbar__section mdc-toolbar__section--align-end" role="toolbar">
<a href="#" id="search-input-open" class="material-icons mdc-toolbar__icon" aria-label="Search" alt="Search">search</a>
<a href="#" class="material-icons mdc-toolbar__icon" aria-label="Login" alt="Login">more_vert</a>
</section>
</div>
</header>
<header class="search-field-phone mdc-toolbar mdc-toolbar--fixed toolbar--custom">
<div class="mdc-toolbar__row">
<a id="search-input-close" class="material-icons mdc-toolbar__menu-icon" tabindex="0">arrow_back</a>
<form action="/search" method="get">
<div class="mdc-text-field mdc-text-field--box autocomplete-search-field">
<input name="q"
type="text"
class="mdc-text-field__input search-input-js aa-input-search"
placeholder="Search for players and videos ..."
aria-label="Full-Width Text Field"
autofocus>
</div>
</form>
</div>
</header>
我遇到的问题是，由于某种原因，下拉菜单在小屏幕上不可见，而在大屏幕上却是。这是scss/css：
.algolia-autocomplete {
display: flex!important;
flex: auto!important;
height: 100%;
}
.aa-dropdown-menu {
position: relative;
top: -6px;
border-radius: 3px;
margin: 6px 0 0;
padding: 0;
text-align: left;
height: auto;
position: relative;
background: $white;
border: 1px solid #ccc;
width: 100%;
left: 0 !important;
box-shadow: 0 1px 0 0 rgba(0, 0, 0, 0.2), 0 2px 3px 0 rgba(0, 0, 0, 0.1);
}
.aa-dropdown-menu .aa-suggestions {
position: relative;
z-index: 1000;
}
.aa-dropdown-menu [class^="aa-dataset-"] {
position: relative;
border: 0;
border-radius: 3px;
overflow: auto;
padding: 0;
color: #3c3e42;
font-weight: 500;
}
.aa-dropdown-menu * {
box-sizing: border-box;
}
.aa-suggestion {
display: block;
width: 100%;
height: 72px;
clear: both;
.mdc-list-item {
height: 72px;
}
}
.aa-suggestion span {
white-space: nowrap !important;
text-overflow: ellipsis;
overflow: hidden;
display: block;
float: left;
line-height: 1em;
width: calc(100% - 30px);
}
.aa-suggestion.aa-cursor {
background-color: transparent;
}
.aa-suggestion em {
color: #00bcd4;
font-weight: 700;
}
.aa-suggestion img {
float: left;
height: 44px;
width: 44px;
margin-right: 6px;
}
.aa-suggestion a {
color: #3c3e42;
}
.aa-suggestions-category {
font-weight: 700;
color: #3c3e42;
border-bottom: 1px solid rgba(102, 105, 105, 0.17);
}
.powered-by-algolia {
padding-left: 15px;
border-top: 1px solid rgba(102, 105, 105, 0.17);
display: flex;
align-items: center;
height: 30px;
}
.aa-input-container {
display: inline-block;
position: relative; }
.aa-input-search {
width: 100%;
height: 30px;
padding: 12px 28px 12px 12px;
box-sizing: border-box;
-webkit-appearance: none;
-moz-appearance: none;
appearance: none; }
.aa-input-search::-webkit-search-decoration,
.aa-input-search::-webkit-search-cancel-button,
.aa-input-search::-webkit-search-results-button,
.aa-input-search::-webkit-search-results-decoration {
display: none;
}
.media {
margin: 10px 0;
}
.media-body {
p {
margin: 0;
}
}
.toolbar--custom {
color: $white;
.mdc-toolbar__row {
min-height: 56px;
}
form, .autocomplete-search-field {
width: 100%;
}
.mdc-text-field--box:not(.mdc-text-field--upgraded) {
height: 36px;
}
.mdc-text-field--box {
overflow: visible;
margin: auto;
.mdc-text-field__icon {
bottom: 8px;
font-size: 22px;
}
}
.mdc-text-field--box:after,
.mdc-text-field--box:before {
top: 0;
left: 0;
width: 100%;
height: 100%;
}
#search-input-open {
display: none;
}
@media only screen and (max-width: 782px) {
#search-input-open {
display: block;
}
.search-field-desktop {
display: none;
}
}
}
.search-field-phone {
clip-path: circle(0%);
visibility: hidden;
.mdc-text-field {
clip-path: circle(0%);
}
}
@mixin search-animated-open {
-webkit-animation: open 0.3s forwards;
animation: open 0.3s forwards;
animation-timing-function: $mdc-animation-standard-curve-timing-function;
}
@mixin search-animated-close {
-webkit-animation: close 0.3s forwards;
animation: close 0.3s forwards;
animation-timing-function: $mdc-animation-standard-curve-timing-function;
}
.search-field-phone-open, {
visibility: visible;
@include search-animated-open;
.mdc-text-field {
@include search-animated-open;
}
}
.search-field-phone-close, {
@include search-animated-close;
.mdc-text-field {
@include search-animated-close;
}
}
@keyframes open {
from {
clip-path: circle(0 at calc(100% - 68px) 50%);
}
to {
clip-path: circle(150% at calc(100% - 68px) 50%);
}
}
@keyframes close {
from {
clip-path: circle(150% at calc(100% - 68px) 50%);
}
to {
clip-path: circle(0 at calc(100% - 68px) 50%);
visibility: hidden;
}
}
整个页面的布局是这样的：
<div id="app">
@include('layouts.partials.sidebar')
@include('layouts.partials.navigation')
<div class="page-content">
@yield('content')
</div>
</div>
导航部分是上面显示的带有标题的文件。这是侧边栏部分：
<aside class="mdc-drawer mdc-drawer--temporary mdc-typography">
<nav class="mdc-drawer__drawer">
<header class="mdc-drawer__header">
<div class="mdc-drawer__header-content">
Header here
</div>
</header>
<nav id="icon-with-text-demo" class="mdc-drawer__content mdc-list">
<a class="mdc-list-item mdc-list-item--activated" href="#">
<i class="material-icons mdc-list-item__graphic" aria-hidden="true">inbox</i>Inbox
</a>
<a class="mdc-list-item" href="#">
<i class="material-icons mdc-list-item__graphic" aria-hidden="true">star</i>Star
</a>
</nav>
</nav>
</aside>
这是页面的css：
body {
margin: 0;
}
#app {
display: flex;
}
.page-content {
display: inline-flex;
flex-direction: column;
flex-grow: 1;
height: 100%;
box-sizing: border-box;
}
我不确定是什么导致了这种行为，为什么大屏幕的下拉菜单可见，而小屏幕的下拉菜单不可见？
更新
我注意到，当我在小屏幕上打开搜索输入时，如果我删除 search-field-phone-open 则下拉菜单可见，我不确定该类中的什么导致下拉菜单不可见？
.search-field-phone-open, {
visibility: visible;
@include search-animated-open;
.mdc-text-field {
@include search-animated-open;
}
}

你好@leff。我无法复制这个问题，因为我在这里缺少一些 JS 和 CSS。你有一个在线页面（也许是 jsfiddle？）我可以看到这个问题吗？

我已将小提琴的链接添加到问题中，但不幸的是我无法让它在那里工作。希望它至少可以让您大致了解我正在尝试做的事情。
