How to keep a dropdown displayed after showing with hover event? - css

Question

I have a header composed of navigation links to other websites, some of these links are shown through drop-down menus.
With the event hover I have added an animation and style to see what you are on at every moment and that, in case of a drop-down, shows you all the options.
The thing is that I don't know how to keep the drop-down menu displayed to select any of the links and that it disappears in case of #mouseleave.
I have tried to take the event #mouseleave to the dropdown itself but it doesn't work.
If someone can make me see my mistake.
Thanks in advance for your time and help.
I leave you a link with a sample which I have it working now

Put the mouseover and mouseleave events on the <li> element that contains both the link and the dropdown.
<li class="nav-item" #mouseover="animalList = true" #mouseleave="animalList = false">
<a class="nav-link menu-link-toggle">PERSONAL FORM</a>
<ul class='dropdown-menu' v-if="animalList">
<li class='dropdown-menu-item'>
<a class='dropdown-menu-link'>DATA</a>
</li>
<li class='dropdown-menu-item'>
<a class='dropdown-menu-link'>FORM DATA</a>
</li>
<li class='dropdown-menu-item'>
<a class='dropdown-menu-link' >AUTOCOMPLETE</a>
</li>
</ul>
</li>
