Select inputs greyed out

I have several select/drop downs on my html page but they all appear in grey - see attached pdf

Here is a section of the html also attached

<div style="clear: left;">
<div class="label" style="clear: left; float: left;">
Mortgage Purpose</div>
<div class="input" style="float: left;">
<select name="ctl00$ContentPlaceHolder1$int_cases_MortgageTypeFK" onchange="javascript:setTimeout(&#39;__doPostBack(\&#39;ctl00$ContentPlaceHolder1$int_cases_MortgageTypeFK\&#39;,\&#39;\&#39;)&#39;, 0)" id="ContentPlaceHolder1_int_cases_MortgageTypeFK">
<option selected="selected" value="">-Select-</option>
<option value="1">Purchase</option>
<option value="3">Purchase - BTL</option>
<option value="6">Purchase - FTB</option>
<option value="4">Purchase - RTB/Current</option>
<option value="5">Remortgage - BTL</option>
<option value="2">Remortgage - Home</option>

</select></div>

Hello,

The reason the drop downs appear in gray is because the API does not support fillable PDF forms. HTML form fields are non-editable in the generated PDF.

None of the other inputs (text boxes & radio buttons) are grayed out so It doesn't make any sense to render the dropdowns in gray.

I would implement pdfcrowd in my software immediately if you can remove this "feature" as any end user inspecting the pdf would think there was something wrong with it.
