我尝试使用下面提到的代码

我已经添加了代码@omisBrown

标签： php dropdown bootstrap-multiselect

【解决方案1】：

使用此脚本为您的多选下拉菜单选择所有功能

html

<select id="lstFruits" multiple>
     <option value="v"><?php echo $vertical_name?></option>
     <option value="c">Contact List</option>
     <option id="select_all">Select All<option>
</select>

$('#select_all').click(function() {
    $('#lstFruits option').prop('selected', true);
});
