How can I adjust the width of a submenu to avoid text wrapping?

Hi there

I would like to know how to change the width of the secondary sub-menu so the menu option is on one line and doesn’t wrap.

Our website is: www.haciendablue.com

When you click on “Shop” → “Homewares” you will see the next sub-menu text is wrapping. Could you please let me know how to change this?

Thank you
