layui下拉選及在layui中使用bootstrap下拉選

<select id="slpk1" data-live-search="true" lay-ignore multiple 
class="selectpicker" data-size="6" data-max-options="1"
data-selected-text-format="count" 
data-live-search-placeholder="搜索"  
data-dropup-auto="false" οnchange="change1()"></select>
<input type="hidden" id="hiddenName1">

lay-ignore 排除layui自帶屬性，能正確顯示搜索框等
data-size=“6” 控制下拉選不要顯示過長
data-dropup-auto=“false” 控制select彈出方向爲下

<select name="city" lay-verify="" lay-search>

lay-search 來開啓layui下拉選的搜索匹配功能
