Hello,

First of all thanks for choosing our Theme, we are glad to be you in the WoodMart WordPress family :-).

I saw the screenshots you attached.

1) Sorry but there is no such option available in theme settings for that. You can try adding the following Custom CSS in the Global Custom CSS area under Theme Settings >> Custom CSS.

.categories-menu-dropdown.vertical-navigation.woodmart-navigation {
	overflow: scroll;
	height: 335px;
}

You can adjust the height according to your needs.

2) By default the arrows and arrows are set to display You can try disabling the option to hide the arrows or dots from the brand’s element by editing the pre-footer HTML.

Regard’s.
