Atleast one drop down value is more than 0 from multiple drop downs - jQuery Validator

Two different drop down selection with jQuery validate validation

Let's use below HTML

// Validate Add Post page At front-end Full Access form
jQuery("#add_post").validate({
  rules:{
    post_title: {
      required: true
    },
    category: {
      require_from_group: [1, ".postselection"]
    },
    group_category: {
      require_from_group: [1, ".postselection"]
    }
  },
  messages:{
    post_title: {
      required: "Please Enter Your Post Title"
    },
    category: {
      require_from_group : "Please select either category or group"
    },
    group_category: {
      require_from_group : "Please select either category or group"
    }
  }
});

<script src="http://ift.tt/1rKdStd"></script>
<script src="http://ift.tt/Y44mcc"></script>
<script src="http://ift.tt/1xh5DvV"></script>
<form action="" method="post" accept-charset="utf-8" id="add_post" name="myform" enctype="multipart/form-data" novalidate="novalidate">

<input type="text" name="post_title" value="" id="post_title" placeholder="Enter Title Here" class="inputtxt">

<select name="category" id="category" class="postselection valid" aria-invalid="false">
<option value="0">Please Select Your Category</option>
<option value="101">Sports</option>
<option value="102">Startups</option>
<option value="103">Travel</option>
<option value="106">Weather</option>
<option value="107">Wisdom</option>
<option value="108">Writing</option>
</select>

OR

<select name="group_category" id="group_category" aria-invalid="false" class="mygroup postselection valid">
<option value="0">Select one of your groups</option>
<option value="11">New Launch Updates</option>
<option value="12">Smile Groups</option>
<option value="13">Social Enterprise</option>
<option value="14">Developers Corner</option>
<option value="15">WordPress</option>       
</select>

<input type="submit" name="submit" value="Submit Post" id="add-new-post">
  
</form>

======================================================================

We have 2 multiple drop down here and I want either one selected both of one and that value must be greater than zero.

By default all drop down selected with first option. So, require_from_group not throwing validation error any time and I must want selection which are not selected by default.

In short,

• 
  

  Either one option selected from numbers of drop downs

  
  


• 
  

  And that value must to zero (default selection)

  
  

(Note: Use JQuery validator for validation is compulsory)

Let me know if you want further explanation with code snippet.

Thanks in advance!
