My menu displays items that correspond to content on another list.
MENU
<ul id="gallery-list" style="display: none;">
<li class="close"></li>
<li data-id="9425"><strong>item 1</strong></li>
<li data-id="9426"><strong>item 2</strong></li>
<li data-id="9488"><strong>item 3</strong></li>
<li data-id="9489"><strong>item 4</strong></li>
<li data-id="9495"><strong>item 5</strong></li>
<li data-id="9427"><strong>item 6</strong></li>
</ul>
CONTENT:
<ul id="gallery-container">
<li data-id="9425">
<h3 style="display: none;">Item 1</h3>
<div class="content">Content here</div>
</li>
<li data-id="9426">
<h3 style="display: none;">Item 2</h3>
</li>
<li data-id="9488">
<h3 style="display: none;">Item 3</h3>
</li>
<li data-id="9489">
<h3 style="display: none;">Item 4</h3>
</li>
<li data-id="9495">
<h3 style="display: none;">Item 5</h3>
<div class="content">Content here</div>
</li>
<li data-id="9427">
<h3 style="display: none;">Item 6</h3>
<div class="content">Content here</div>
</li>
</ul>
Some items have a .content class within the li in the content section. How can I use the data-id attribute to show only relevant items in the menu? Essentially, only items with a .content class should be displayed in the menu.
The desired output for the MENU is as follows:
<ul id="gallery-list" style="display: none;">
<li class="close"></li>
<li data-id="9425"><strong>item 1</strong></li>
<li data-id="9495"><strong>item 5</strong></li>
<li data-id="9427"><strong>item 6</strong></li>
</ul>
An alternative acceptable format could be:
<ul id="gallery-list" style="display: none;">
<li class="close"></li>
<li data-id="9425"><strong>item 1</strong></li>
<li data-id="9425" style="display:none;"><strong>item 2</strong></li>
<li data-id="9425" style="display:none;"><strong>item 3</strong></li>
<li data-id="9425" style="display:none;"><strong>item 4</strong></li>
<li data-id="9495"><strong>item 5</strong></li>
<li data-id="9427"><strong>item 6</strong></li>
</ul>
Note that items in the content are initially set to display:none;.
This script manages the display of list contents and activates the menu:
$("#gallery-list li").click(function() {
var id = $(this).data('id');
$("#gallery-container").find('li').each(function() {
$(this).find('.content').toggle($(this).data('id') === id);
$(this).find('h3').toggle($(this).data('id') === id);
});
});
window.onload = function () {
$("#gallery-container li .content").css("display", "none");
$("#gallery-container li h3").css("display","none");
$("#gallery-container li p").css("display","none");
}
$('.gallery-menu h3, #gallery-list li').click(function(){
$("#gallery-list, .gallery-menu h3").toggle();
});
This functionality controls the visibility of list items based on the content's .content class and triggers the menu.
