ignore me... my css to give padding to bullet points also affected the mega menu ul li, ol li { margin-bottom: 10px; }

Hi,

ignore me...

As you wish ;p

But I have extra small tip that may help a little bit users to click on first submenu items.

.sp-megamenu-parent .sp-dropdown .sp-dropdown-inner {
  padding: 5px 10px; }

default value is 20px (top, right, botton, left) reducing top value - helps - 15px makes a difference.

see below.
