<ul class="nav navbar-nav">
<li class="nav-item-dropdown">
<a class="nav-link dropdown-toggle" data-toggle="dropdown" href="#" role="button" aria-haspopup="true" aria-expanded="false">

<div class="dropdown-menu" aria-labelledby="Preview">
<a class="dropdown-item" href="#">Événements Importants</a>

<a class="dropdown-item" href="#">Rappel CRA</a>
<a class="dropdown-item" href="#">Visite Client</a>

</div>
</li>
<li class="nav-item">
<a class="nav-link" href="#">POP-UP</a>

</ul>
Here's my code
The problem is that there's no padding, is it normal ? Here's a picture of what it renders :

Other problem is that it can display you 2 links on the same line :/

Answer 1

I fail to make your dropdown work, but you can add some padding to your a elements like this:
In HTML:
...
<a class="dropdown-item pad15" href="#">Événements Importants</a>
...
In CSS:
.pad15 {
padding: 15px;
}
It is very simple, but I guess it is what you are looking for.
UPDATE: Without CSS file
...
<a class="dropdown-item" style="padding:15px;" href="#">Événements Importants</a>
...
