    <p>I have one text input box</p> <pre><code>&lt;input type="text" id="search" /&gt; </code></pre> <p>and <strong>multiple HTML-tables</strong> like this: </p> <pre><code>&lt;table id="table1"&gt; &lt;thead&gt; &lt;tr&gt; &lt;th&gt;Table1 title&lt;/th&gt; &lt;/tr&gt; &lt;tr&gt; &lt;th&gt;Name&lt;/th&gt; &lt;th&gt;Country&lt;/th&gt; &lt;/tr&gt; &lt;/thead&gt; &lt;tbody&gt; &lt;tr&gt; &lt;td&gt;Andrew&lt;/td&gt; &lt;td&gt;USA&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;John&lt;/td&gt; &lt;td&gt;Canada&lt;/td&gt; &lt;/tr&gt; &lt;/tbody&gt; &lt;/table&gt; </code></pre> <p>I want to filter data depending on what user types in the input box.</p> <p>Now my JS code is:</p> <pre><code>$(document).ready(function(){ $("#search").keyup(function(){ // When value of the input is not blank if( $(this).val() != "") { // Show only matching TR, hide rest of them $("#table1 &gt; tbody &gt; tr").hide(); $("#table1 td:contains-ci('" + $(this).val() + "')").parent("tr").show(); } else { // When there is no input or clean again, show everything back $("#table1 tbody &gt; tr").show(); } }); }); // jQuery expression for case-insensitive filter $.extend($.expr[":"], { "contains-ci": function(elem, i, match, array) { return (elem.textContent || elem.innerText || $(elem).text() || "").toLowerCase().indexOf((match[3] || "").toLowerCase()) &gt;= 0; } }); </code></pre> <p>Everything works OK.</p> <p>But now I want to hide a whole table including thead TR's if a typed text is not in the table.</p> <p>How can I get that?</p>

Guidance
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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
