效果图

改动

有时ID并不是顺序的,优化的加入了id监听

<div class="form-group">
    <label>选择类目</label>
    <br>
    <select id="type1" class="custom-select form-control col-12 col-md-3 mt-3 mr-3" name="type1">
        <option value="-1">请选择</option>
    </select>

    <select id="type2" class="custom-select form-control col-12 col-md-3 mt-3 mr-3" name="type1">
        <option value="-1">请选择</option>
    </select>

    <select id="type3" class="custom-select form-control col-12 col-md-3 mt-3 mr-3" name="type1">
        <option value="-1">请选择</option>
    </select>

    <br>
    <input name="type1_id" id="type1_id" value="" hidden="didden" />
