Below the CSS used also in the second link:
.dropdown-submenu {
position: relative;
}
.dropdown-submenu>.dropdown-menu {
top: 0;
left: 100%;
margin-top: -6px;
margin-left: -1px;
-webkit-border-radius: 0 6px 6px 6px;
-moz-border-radius: 0 6px 6px;
border-radius: 0 6px 6px 6px;
}
.dropdown-submenu:hover>.dropdown-menu {
display: block;
}
.dropdown-submenu>a:after {
display: block;
content: " ";
float: right;
width: 0;
height: 0;
border-color: transparent;
border-style: solid;
border-width: 5px 0 5px 5px;
border-left-color: #ccc;
margin-top: 5px;
margin-right: -10px;
}
.dropdown-submenu:hover>a:after {
border-left-color: #fff;
}
.dropdown-submenu.pull-left {
float: none;
}
.dropdown-submenu.pull-left>.dropdown-menu {
left: -100%;
margin-left: 10px;
-webkit-border-radius: 6px 0 6px 6px;
-moz-border-radius: 6px 0 6px 6px;
border-radius: 6px 0 6px 6px;
}
Actually the second dropdown I wanted to behave like the menus of any program that will open tabs to the side. The first dropdown would be down and the others down and to the side. As in the windows menu.

How is the CSS?
– user3453562
in this case I am using the pure bootstrap even with the "Caret".
– user65509
.Caret { display: inline-block; width: 0; height: 0; margin-left: 2px; vertical-align: Middle; border-top: 4px dashed; border-top: 4px Solid 9; border-right: 4px Solid Transparent; border-left: 4px Solid Transparent; }
– user65509
it works only with a dropdown, the Caret only makes the indication triangle as far as I know. the dropdown-menu that makes the downward movement.
