Hikashop dropdowns not working

Hi friends,
I'm having a problem with Storefront and Hikashop. As you can see on this page, I'm trying to offer a product option for an extended warranty: https://sptlt.com/products/detectors/product/delta-4000

However, the drop-down doesn't seem to work. Switching to the default Joomla theme seems to fix the problem. Any help would be greatly appreciated!

SOLVED: I added this line of code:

#hikashop_product_option_0 {
display: inline !important;
height: 20px;
}

Hi

Glad to hear that and thank You for shearing solution with us.
