Как сделать фильтр?

<div>
  <input type="checkbox" id="condition">

  <div condition="true">condition</div>
  <div condition="false">condition</div>
</div>

div[condition] {display: none;}
#condition:checked ~ div[condition="true"] {display: block;}
#condition:not(:checked) ~ div[condition="false"] {display: block;}

<div>
  <input onclick="hideCondition(event)" type="checkbox" id="condition">
</div>
<div>
  <div condition="true">condition</div>
  <div condition="false">condition</div>
</div>

function hideCondition(e) {
    $('div[condition]').hide();
	if (e.target.checked) $('div[condition="true"]').show();
}
