Invisible Text in Search items box for Menu and variable price

Thanks for contacting us. You can use the following CSS to make sure that text in the input box displays properly.

.fdm-menu-filtering input.fdm-filtering-text-input {
padding: 0 10px !important;
line-height: 1 !important;
color: black !important;
}

You can add this CSS to the active theme's style.css
