Hello,
First of all thanks for choosing our Theme, we are glad to be you in the WoodMart WordPress family :-).
Unfortunately, There is no option in Theme Settings available to hide the categories and show only icon.
You need to add the following Custom CSS code to hide the text categories from the categories menu in the Global Custom CSS area under Theme Settings >> Custom CSS.
.menu-open-label {
display: none;
}
Note: This will only hide the text browse categories from the categories menu.
Best Regards.
.
