Filtering
Isotope can hide and show item elements via the filter
option. filter
accepts a jQuery selector. Items that match that selector will be shown. Items that do not match will be hidden.
Markup
Each item element has several identifying classes. In this case, transition
, metal
, lanthanoid
, alkali
, etc.
<div id="container">
<div class="element transition metal">...</div>
<div class="element post-transition metal">...</div>
<div class="element alkali metal">...</div>
<div class="element transition metal">...</div>
<div class="element lanthanoid metal inner-transition">...</div>
<div class="element halogen nonmetal">...</div>
<div class="element alkaline-earth metal">...</div>
...
</div>
jQuery script
To show only .metal
items, the jQuery script would be:
$('#container').isotope({ filter: '.metal' });
Filtering selectors work just as expected. .alkali, .alkaline-earth
will show both .alkali
AND .alkaline-earth
items, and hide all others. .metal.transition
will show elements that have both .metal
and .transition
classes. .metal:not(.transition)
will show .metal
item elements that are not .transition
.
Creating interactive buttons
Let’s use a basic list for our buttons
<ul id="filters">
<li><a href="#" data-filter="*">show all</a></li>
<li><a href="#" data-filter=".metal">metal</a></li>
<li><a href="#" data-filter=".transition">transition</a></li>
<li><a href="#" data-filter=".alkali, .alkaline-earth">alkali and alkaline-earth</a></li>
<li><a href="#" data-filter=":not(.transition)">not transition</a></li>
<li><a href="#" data-filter=".metal:not(.transition)">metal but not transition</a></li>
</ul>
Here we set the filter for each link with a data-filter
attribute. In our jQuery script, whenever a link is clicked, we’ll use this attribute as the filter selector.
$('#filters a').click(function(){
var selector = $(this).attr('data-filter');
$('#container').isotope({ filter: selector });
return false;
});
Recommended CSS
If you choose to use the filtering functionality, add the following CSS to your stylesheet:
/**** Isotope filtering ****/
.isotope-item {
z-index: 2;
}
.isotope-hidden.isotope-item {
pointer-events: none;
z-index: 1;
}
These styles ensure that hidden items will not interfere with interactions.
