Woocommerce过滤文字宽度

I have started to design a new site to my cousins and decided to use woocommerce as filter options is what we need. All products shall be filtered by their attributes. I put woocommerce filter widget on sidebar. But the text in the dropdown is not a single line in one attribute. It is on 2 line even it is a short attribute.

Shows where this issue occurs

I have realized that all 3 filters have different width in the style;

<span class="widgetSelect dropdown_layered_nav_tamirci" style="display: inline-block;">
<span class="widgetSelectInner" style="width: 225px; display: inline-block;">Hangi Tamirci</span>
</span>


<span class="widgetSelect dropdown_layered_nav_sehir" style="display: inline-block;">
<span class="widgetSelectInner" style="width: 73px; display: inline-block;">Hangi Şehir</span>
</span>

<span class="widgetSelect dropdown_layered_nav_ilce" style="display: inline-block;">
<span class="widgetSelectInner" style="width: 77px; display: inline-block;">Hangi İlçe</span>
</span>

I found in woocomerce plugin "wp-content/plugins/woocommerce/includes/widgets" class-wc-widget-layered-nav.php file has something but I couldnt manage to figure it out.

I have added below code but it didn't work;

.savilerowSelect .savilerowSelectInner,

.widgetSelect .widgetSelectInner {

width: 100%;

}

How can I make this filters one line?

Thank you.
