title: Scrolling locked in iOS
body: <p>I have a weird issue on my mobile website when viewed in Safari on an iPhone (5, 6). When i open the left slide menu and then open a submenu (i.e. Electrical Solutions) that has considerably many items that cannot fit vertically on the screen, the scroll down touch gets locked and can't view the remaining elements in the submenu. However, if i open another Submenu (i.e. Industries) with the previous Submenu kept open, the scroll down unlock and works normally and now i can view the other elements in the first submenu.
  What i tried: I checked the <code>overflow</code> in all these elements and nothing looks wrong and also added the <code>-webkit-overflow-scrolling</code> touch to the body but still no luck.
  What are my other options to check?</p>
