Select "arrow" hidden in bootstrap 3 input group in IE9

Question

I have the following html styled by bootstrap 3 that defines a group of inputs:

<div class="input-group">
    <select class="form-control" >Some options here</select>
    <a class="btn btn-default input-group-addon disabled" title="Legg til" disabled="" href="#" ><i class="glyphicon glyphicon-plus-sign"></i></a>
</div>

This gives the following result in most browsers (including IE10):

However in IE9, the "arrow" for the dropdown is missing:

Anyone know a fix for this in IE9?

Answer 1

I found the issue here. It seems that the arrow button is simply hidden below the button with the plus icon. So the select box is the entire width, and the other buttons end up overlying it.

So the fix was to add float:left to the select box, and voila!
