How can I use JavaScript to execute a function when clicking on a notification button in a Bootstrap navbar to expand the dropdown, and then close the dropdown when clicking it again?
I have tried selecting the dropdown and modifying the click function, but it only executes when clicking an element within the dropdown, not the button itself.
#ex4 {
color: white;
width: auto;
}
#ex4 .p1.has-badge:after {
position: absolute;
right: 10%;
top: 8%;
content: attr(data-count);
font-size: 40%;
padding: .2em;
border-radius: 50%;
line-height: 1em;
color: white;
background: rgba(255, 0, 0, .85);
text-align: center;
min-width: 1.5em;
}
form.logout {
padding-left: 10px;
