2. You could try:

#menu-my-list-of-categories .sub-menu {
  display: none !important;
}
#menu-my-list-of-categories li:hover .sub-menu {
  display: block !important;
}

OR

#menu-my-list-of-categories .sub-menu {
  display: none !important;
}
#menu-my-list-of-categories li:active .sub-menu {
  display: inline !important;
}

OR

#menu-my-list-of-categories .sub-menu {
  display: none !important;
}
#menu-my-list-of-categories li:active .sub-menu {
  display: block !important;
}

3b. Looking at your screen (http://prntscr.com/19x7p9), see where the following line for example is:

<p>Name *<br />

Update to:

<p>Name <span class="aster">*</span><br />

4. Something like this?:

.widget-container {
  min-height: 200px;
}
#menu-my-list-of-categories li a {
  border: 1px solid #666666;
  display: inline-block;
  margin: 3px 0;
  padding: 2px 5px;
  width: 80%;
}
