    text
    copied!<p>I'm having trouble using the preserve method in meteor. It doesn't seem to do what I want it to do. </p> <p>Basically, I have three nested templates which, when rendered, look something like this in their <strong>closed state</strong>:</p> <pre><code>&lt;div class="Dropdown"&gt;&lt;!--From Template1--&gt; &lt;div class="Group"&gt;&lt;!--From Template2--&gt; &lt;div class="SubGroup"&gt;&lt;!--From Template3--&gt; I'm the subgroup's content! &lt;/div&gt; &lt;/div&gt; &lt;/div&gt; </code></pre> <p>To view the content in the .SubGroup node, all template wrappers need to bear the .Open class name. This is done on a click event. Here's what it looks like in <strong>open state</strong>:</p> <pre><code>&lt;div class="Dropdown Open"&gt;&lt;!--From Template1--&gt; &lt;div class="Group Open"&gt;&lt;!--From Template2--&gt; &lt;div class="SubGroup Open"&gt;&lt;!--From Template3--&gt; I'm the subgroup's content! &lt;/div&gt; &lt;/div&gt; &lt;/div&gt; </code></pre> <p>The issue is, when events fire and alter the database from within .SubGroup's content, it looks like <strong>Template2 and Template3 both get re-rendered and lose their programmatically applied .Open class</strong>. </p> <p>I've tried using <code>Template.Template2.preserve(['.Group']); </code> on each template with just about every selector I think could affect it. I've also tried {{#constant}} and {{#isolated}} helpers, but have yet to get expected results with these.</p> <p><strong>What's the right way to keep Meteor from wiping my class names out?</strong></p>
