css - Navbar second submenu not positioned correctly -


this question based on thread here on here works fine, unless 2nd level item not on top. in example given, item 2nd level menu first item. if move item down 1 or 2 spots, 2nd level opens @ top.

the css, looks good, thought maybe had bootstrap version in 1 demo link in thread

    .sidebar-nav {     padding: 9px 0; }  .dropdown-menu .sub-menu {     left: 100%;     position: absolute;     top: 0;     visibility: hidden;     margin-top: -1px; }  .dropdown-menu li:hover .sub-menu {     visibility: visible; }  .dropdown:hover .dropdown-menu {     display: block; }  .nav-tabs .dropdown-menu, .nav-pills .dropdown-menu, .navbar .dropdown-menu {     margin-top: 0; }  .navbar .sub-menu:before {     border-bottom: 7px solid transparent;     border-left: none;     border-right: 7px solid rgba(0, 0, 0, 0.2);     border-top: 7px solid transparent;     left: -7px;     top: 10px; } .navbar .sub-menu:after {     border-top: 6px solid transparent;     border-left: none;     border-right: 6px solid #fff;     border-bottom: 6px solid transparent;     left: 10px;     top: 11px;     left: -6px; }

(fiddle).

so eliminate issue, moved around in sandbox, fiddle, , got same issue, seems not code, or bootstrap version. not attached doing way, open using different, long can have 2nd level menu, , open on hover on full size screens.

thanks,

dave

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
