I am trying to use jquery mobiles custom select with filterable feature for multiselect.
It works great when I dont filter the options. But when I filter the option the selection is not happening properly.
It checks some other option from the list.
In jsfiddle demo, once u open the dropdown, I which will apply the filter and then try to select English and see the issue
Below it the code
<div class="page_1">
<!-- Form Starts -->
<div class="form_wrap" id="form_wrapper">
<form method="post" name="frm_registration" autocomplete="off" style="margin:0px">
<div class="formfd_wrap ">
<label>Mother Tongue</label>
<select id="mother_tongue" name="mother_tongue" multiple="multiple" data-native-menu="false" class="filterable-select reg_inputdrpbox">
<option value="Assamese" >Assamese</option>
<option value="Bengali" >Bengali</option>
<option value="English" >English</option>
<option value="Gujarati" >Gujarati</option>
<option value="Hindi" >Hindi</option>
<option value="Kannada" >Kannada</option>
<option value="Odia" >Odia</option>
<option value="Pashto" >Pashto</option>
<option value="Persian" >Persian</option>
<option value="Punjabi" >Punjabi</option>
<option value="Rajasthani" >Rajasthani</option>
<option value="Russian" >Russian</option>
<option value="Sanskrit" >Sanskrit</option>
<option value="Sindhi" >Sindhi</option>
<option value="Sinhala" >Sinhala</option>
<option value="Spanish" >Spanish</option>
</select>
</div>
</form>

I have tried many things but couldn't solve it.
You can check the custom select menu with filter here on jquery demo page.
