I am currently programing using eclipse, In my app I have a drop dwon menu (select) with a couple of items in it. I am trying to change the width of the select item, but it doesnt work. here you can see what have i done to solve this:

<label for="select-choice-1" class="select">Choose Expiry Date</label>
        <select id="date" name="select-choice-1" id="select-choice-1" style="width:150px">
        <option value="">1</option>
        <option value="">2</option>
        <option value="">3</option>
        <option value="">4</option>
</select>

Answer 1

$('#date').css('width', 'new_Value');

From jQuery Mobile Documentation:

Refreshing a select

If you manipulate a select via JavaScript, you must call the refresh method on it to update the visual styling. Here is an example:

var myselect = $("select#foo");
myselect[0].selectedIndex = 3;
myselect.selectmenu("refresh");
