Hi,
Without seeing the url it makes it more difficult to us to simulate the same situation.
Try to add the code below to your custom css option inside the theme options.
Adjust to the desired width:
nav .mega-menu ul.mega-sub-menu li.mega-menu-item>a, nav .mega-menu ul.mega-sub-menu li>span, nav.std-menu ul.mega-sub-menu {
width: 250px!important;
}
for the button it’s difficult to tell but try to play around with the line height value.
#header .std-menu ul.mega-menu > li > a.sf-button > span, #header .std-menu ul.menu > li > a.sf-button > span {
line-height: 52px;
}
