Select is not optional in IE

Because jquery is recently used, JS is written in the jquery format.

 

Code

1 <select name = "drpadaddress" id = "drpadaddress">
2 <option value = "0"> select </option>
3 <option value = "0" Disabled = "true"> homepage </option>
4 <option value = "4"> | --- homepage header </option>
5 <option value = "6" >|--- homepage left </option>
6 <option value = "7"> | --- Right of the homepage </option>
7 <option value = "0" Disabled = "true"> List page </option>
8 <option value = "9" >|--- left of the List </option>
9 <option value = "0" Disabled = "true"> news page </option>
10 <option value = "0" Disabled = "true"> Print the product page </option>
11 <option value = "19" >|--- printing </option>
