Just need a little bit of help with some coding.
Trying to create a dropdown directory list of photo galleries, which only appears on Mobile devices (Thanks Hide!)
The list contains links that take you to the relevant page with the photos.
However, I cannot get it to collapse once you press it to open.
The webpage is as follows: - In order to view the button, you must view it on a "Medium or Small" screen.

The code I'm using is as follows;
<style>
.wcustomhtml
{
overflow: visible !important;
}
.dropbtn {
background-color: #a1a1a1;
color: white;
min-width: 250px;
padding: 16px;
font-size: 16px;
border: none;
}
.dropdown {
position: relative;
display: inline-block;
}
.dropdown-content {
display: none;
position: absolute;
background-color: #f1f1f1;
min-width: 250px;
box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
z-index: 1;
}
.dropdown-content a {
color: black;
padding: 12px 16px;
text-decoration: none;
display: block;
}
.dropdown-content a:hover {background-color: #ddd;}
.dropdown:hover .dropdown-content {display: block;}
.dropdown:hover .dropbtn {background-color: a1a1c1;}
</style>
<div class="dropdown">
<button class="dropbtn">Photo Galleries</button>
<div class="dropdown-content">

</div>

Can anyone please help me with what I'm missing?! I just need it to collapse when you press it again.
Many thanks in advance!
I won't be able to help out, unfortunately, but I'm sure we have a user or two on here that can.
