<select> only shows first char of selected option

I have a standard select box which I'm populating using jquery by appending options, but for some reason IE9 only shows the first character of the selected option. Needless to say it works perfectly in FireFox and Chrome, but I have to support IE9. I tried the IE9 compatibility modes, but it made no difference, nor does styling the select or option.

Has anyone seen this issue before. What caused it? How did you fix it?

Simplified code sample:

<select id="selectCCY" ValueColumn="ccyID" DisplayColumn="ccySymbol" ></select>



$.each(res.result, function (key, value) {  
    $('#selectCCY').append('<option value="' + value[$('#selectCCY').attr('ValueColumn')]+ '">' + value[$('#selectCCY').attr('DisplayColumn')] + '</option>');
});

res.result is a simple json array like this:

[{"ccyID":1,"ccySymbol":"GBP"},{"ccyID":2,"ccySymbol":"AUD"},{"ccyID":3,"ccySymbol":"USD"}]

OH BUGGER!!! it works fine in my simplified example, so the problem is somewhere else. Sorry. The original code is to long and complex to paste here, but will let you know when I find the answer.

some time later....

OK, I got the problem down to an ajax call inside a $(selector).each() loop. The loop goes through all select boxes and asyncronously populates the options. If I make it a syncronous call, the select boxes have the correct width and show correctly, but if its an async call the select boxes only show the first char as in the image. still working on this, will get back to you again.

I still want to know what would cause a select box to display incorrectly. I can do workarounds and get it to show correctly, but that doesn't answer the question. It's just a select with options in it, it should always just work, right?

after a weekend of ignoring the issue ....

Right I found a workaround. Before doing the ajax call to populate the select box I first set the css display property to 'none' on it, then populate it and finally when the ajax call and population is complete I just remove the css display 'none' property.

So I still don't know why IE doesn't like me, but we have a solution at least.

It is an IE only problem. First set the css display property on the select box to 'none', then populate it via your ajax call, finally when the ajax call is done and the select box is populated remove the css display 'none' property on the select box
