Hello,

#15 Navigate to Appearance > Menu > enter menu item and set the mouse event http://prntscr.com/kvj6tq

Browse Categories can be set to be always open or open on hover, Pages > edit page and set in the page settings.

Do you mean problems with SVG? If so:
You need to open your SVG icons file with some editor like Sublime Text or default system text editor and add height and width attributes to your <svg> tag like it is shown: http://prntscr.com/kvj843

Then you will need to re-upload your icons in WordPress Dashboard.

Best Regards
