Icon sort by on mobile

Hello there,
I’d like to get rid of the icon sort products by on woocommerce archive and instead show a classic dropdown

This happens by removing the following class:
class=”woocommerce-ordering wd-style-underline wd-ordering-mb-icon”

On the following script

<form class="woocommerce-ordering wd-style-underline wd-ordering-mb-icon" method="get">
			<select name="orderby" class="orderby" aria-label="Ordine negozio">
							<option value="date" selected="selected">Ordina in base al più recente</option>
							<option value="price">Prezzo: dal più economico</option>
							<option value="price-desc">Prezzo: dal più caro</option>
					</select>
		<input type="hidden" name="paged" value="1">
			</form>

What I want to achieve is a regular full width dropdown on mobile but apart from removing the class I couldn’t figure out what css to edit.
I provide you with screenshot

Thanks
