<select name="syearid" class="select2_group form-control"  style="text-align:center;text-color:white;display:none;" > 

display:none; hide select tag.

note can (better):

<style>     #syearid{text-align:center;text-color:white;display:none;} </style> <select id="syearid" name="syearid" class="select2_group form-control" >

to pre-set value, , disable control, can this:

<select disabled>   <option>car</option>   <option selected>bus</option>   <option>van</option> </select>
