From the following files :
/app/design/frontend/base/default/template/customer/form/register.phtml /app/design/frontend/base/default/template/customer/form/address.phtml /app/design/frontend/base/default/template/checkout/onepage/billing.phtml and /app/design/frontend/base/default/template/checkout/onepage/shipping.phtml
i did this trick converting php line
<?php echo $this->getCountryHtmlSelect() ?>
to html line
<select name="country_id" id="country" title="<?php echo $this->__('Country') ?>" class="validate-select">
<option value="IN" selected="selected">India</option>
</select>
but not worked. In site showing one blank line and other line India.
I need only one line India or remove dropdown.
