    <p>my first Question so please be patient. I have a container that holds a varying number of child elements like this:</p> <pre><code>&lt;div class="parent"&gt; &lt;div class="element"&gt;content&lt;/div&gt; &lt;div class="element"&gt;content&lt;/div&gt; &lt;div class="element"&gt;content&lt;/div&gt; &lt;/div&gt; </code></pre> <p><strong>Quick Question:</strong> Is there a jQuery or plain JS way of checking whether an <code>element</code> container would be visible independent of the <code>parent</code> being visible? </p> <p>Simply asking for </p> <pre><code>jQuery('.parent .element:visible').length </code></pre> <p>does <strong>not</strong> work. </p> <p><strong>Background:</strong> The <code>parent</code> container can be toggled, and the content of the child <code>element</code>s gets fetched by ajax requests and is filled when the response arrives. On every response I get, the child containers get specific classes indicating the type of the response, e.g. <code>available</code>, <code>unavailable</code> and some more. So the resulting DOM may look like this:</p> <pre><code>&lt;div class="parent"&gt; &lt;div class="element available"&gt;content&lt;/div&gt; &lt;div class="element unavailable"&gt;content&lt;/div&gt; &lt;div class="element unavailable"&gt;content&lt;/div&gt; &lt;/div&gt; </code></pre> <p>This is a module, that is used several times with different CSS files. So I do not control whether the CSS implementation actually hides <code>unavailable</code> elements because this is done only in CSS. And the container can be open, but does not have to. But I have to know if there would be visible elements inside of the container without opening it. Is this possible?</p> <p>Thanks in advance!</p>

    1. COGenerally, if a parent is invisible, it's children are implicitly.

    2. COYes thats true, but maybe there is a way to filter out the inherited styles or circumvent this problem nevertheless?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
