My navbar is displaying two collapse menus, but when one is active and I open the second one, the collapsed content from the second menu gets added to the end of the first one's content. How can I close the other menu when opening the second one?
html {
position: relative;
min-height: 100%;
}
body {
margin-bottom: 60px;
}
.footer {
position: absolute;
bottom: 0;
width: 100%;
height: 60px;
line-height: 60px;
/* Vertically center the text there */
background-color: #AD2D2D;
