Question

所以我有引导崩溃，在其中我有标签，并且在其中一个标签中我有一个带有text_field的表单，其中包含bootstrap typeahead，问题是typeahead的下拉列表不会在崩溃时展开。

具有自动填充功能的text_field是其中的最后一个元素。

我希望下拉列表在展开元素下方（图片中的线下方）展开

修改：这是该视图的haml





- @i = 0
- @trainings.each do |training|
  - @i = @i+1
  .accordion#accordion2
    .accordion-group
      .accordion-heading
        %a{:class => 'accordion-toggle', 'data-toggle' => 'collapse', :href => "#collapse#{@i}"}
          = "Training #{@i}"
        %div{:id => "collapse#{@i}", :class => 'accordion-body collapse'}
          .accordion-inner
            %pre= "Description: #{training.description}"
            %ul.nav.nav-tabs#myTab
              %li.active
                %a{"data-toggle" => "tab", :href => "#planirano#{@i}"} Planirano
              %li
                %a{"data-toggle" => "tab", :href => "#napravljeno#{@i}"} Napravljeno
            .tab-content
              %div{:class => 'tab-pane active', :id => "planirano#{@i}"}
                - training.exercises.each do |exercise|
                  %pre= "#{exercise.element.name} | #{exercise.description} | #{exercise.number_of_series}"
                = form_for :training_exercise, :url => training_exercises_path(:training => training.id), remote: true, html: {:class => 'form-inline'} do |f|
                  = f.label :exercise
                  = f.text_field :exercise, :id => 'add_training_exercise'
                  = f.button :Add, :class => 'btn'
              %div{:class => 'tab-pane', :id => "napravljeno#{@i}"} to sam napravio

f.text_ifeld：exercise，：id =＆gt; 'add_training_exercise'是我要问的自动填充字段。

and here is the rendered HTML

Answer 1

我以某种方式找到堆栈溢出的答案，解决方案是

.accordion-body.in {溢出：可见; }

来自here。

我很抱歉提出已经有答案的问题，但我真的无法找到它，因为我没有猜到正确的搜索词。

Answer 2

应用以下css只能部分工作，accordion-body.in {overflow：visible;因为它只显示＆＃34; slice＆＃34;的溢出。正在扩大。您也需要将其应用于父母。另外上面的css影响扩展/倒塌效果;即所显示的内容在手风琴上显示，而不是逐渐显示。我尝试的解决方案是：

1. Apply the overflow:visible only to the parent, i.e. #myAccordion { overflow:visible } AND 
2. Apply overflow:visible only to the "slice" being opened when it is needed (on open), and removing it on close, like so:

    $("#myAccordion").collapse();
    // Here, we are attaching event handlers to the accordion "slice" body so that we can update it's overflow when opened AND when it's about to be closed.
    $("#myAccordion .accordion-body").on("shown", function () {
        $(this).css("overflow", "visible");
    });
    $("#myAccordion .accordion-body").on("hide", function () {
       $(this).css("overflow", "hidden");
    });

Answer 3

这对我有用，因为我的预先输入是在导航栏中

.navbar-collapse.in{
    /*allows typeahead to overflow nav bar during collapse*/
    overflow-y:initial !important;
}

bootstrap typeahead下拉列表不会因为bootstrap崩溃而扩展
