好的，我正在尝试使用css和divs spans创建自定义html选择框。 我没有看到任何错误，但不知道为什么它不能正常工作
以下是fiddle
<div class="ik_select episodes_list_selectbox ik_select_autowidth" style="position: relative; width: 258px;">
<div class="ik_select_link episodes_list_selectbox-link">
<div class="ik_select_link_text">active opt 4</div></div>
<div class="ik_select_dropdown episodes_list_selectbox-dd" style="position: absolute; z-index: 9998; width: 100%; display: none;">
<div class="ik_select_list" style="position: relative;">
<div class="ik_select_filter_wrap">

基本的选择语句如下：
a:link, a:visited{
text-decoration: none;
display: inline-block;
color: black;
background-color: white;
}
a:hover, a:focus, a:active{
text-decoration: none;
display: inline-block;
color: white;
background-color: black;
}

根据选择部分的考虑，您应该使用内置的选择 - 选项对来完美地工作。如果您坚持使用DIV用于此目的，那么您必须在那里使用一些JavaScript才能使其正常工作。
根据我的意见，您应该自定义select-option以便为您工作，
import pandas as pd
from sklearn.cross_validation import train_test_split
from sklearn import svm
from time import time
dum_data = pd.read_csv("dummy_variable_file.csv")
train_cols = dum_data.columns[5:]
target = dum_data.columns[4]
x = dum_data[train_cols]
y = dum_data[target]
x_train, x_test, y_train, y_test = train_test_split(x, y, random_state=442, train_size=0.70)
clf = svm.SVC(probability = True)
model = clf.fit(x_train,y_train)
output_predict_test = model.predict(x_test)
output_proba_test = model.predict_proba(x_test)
output_decision_test = model.decision_function(x_test)

根据项目的性质，使用div元素来设置select样式的原因有多种，这可能是一个坏主意。仅举几例：
如果您需要完整的详细信息，请参阅here主题的非常好的文章。
如果你仍然认为你需要这个，我怀疑你试图修复你提供的JSFiddle将提供良好的投资回报。你需要更多的东西来获得一个很好的选择（包括一些不可忽视的JavaScript）。我建议的是调查流行的现有解决方案来实现目标，例如：
