Same problem here in v1.13.1, when adding subtext that is really long, the dropdown menu becomes too wide and the text does not wrap when exceeding the selector's width. I've tried to set data-width attribute, but that doesn't affect the dropdown menu. Spent several hours to implement a hack to get this fixed, but nothing seems to work so far.

Fixed (but it's a hack):
```
.bootstrap-select .dropdown-menu {
width: 100%;
}
.bootstrap-select .dropdown-menu li small {
white-space: normal;
}
Fixed (but it's a hack):
.bootstrap-select .dropdown-menu { width: 100%; } .bootstrap-select .dropdown-menu li small { white-space: normal; }
if fix by this way, data-size not working
