    <p>I am developping a condition for my site, so that when i scroll my page to an anchor, the menu item corresponding to that anchor adds or removes a certain class.</p> <p>My problem is that i can't make the first item menu remove class, when scrolling to the second anchor, i think the problem may be in the condition, it may not be working the way i think so i need your help</p> <p>For this I am using jquery and here is what i've got so far:</p> <pre><code>jQuery(document).ready(function($) { var target1 = $("#thehotel").offset().top; var target2 = $("#thecity").offset().top; var interval = setInterval(function() { // i am not sure if this setInterval method is causing the problem, yet i didn't find any other solution if ($(window).scrollTop() &gt;= target1 &amp;&amp; $(window).scrollTop() &lt; target2) { $("#menu .item-109 a").addClass("myClass"); $("#menu .item-111 a").removeClass("myClass"); } else if ($(window).scrollTop() &gt;= target2) { $("#menu.item-109 a").removeClass("myClass"); $("#menu .item-111 a").addClass("myClass"); } }, 250); }); </code></pre> <p>I apologize if you find my english bad, it's not my mother language. Thank you.</p> <p><strong>I found my error, it is a typo!</strong></p> <p>here:</p> <pre><code> if ($(window).scrollTop() &gt;= target1 &amp;&amp; $(window).scrollTop() &lt; target2) { $("#menu .item-109 a").addClass("myClass"); $("#menu .item-111 a").removeClass("myClass"); } else if ($(window).scrollTop() &gt;= target2) { //change this $("#menu.item-109 a").removeClass("myClass"); //to this $("#menu .item-109 a").removeClass("myClass"); $("#menu .item-111 a").addClass("myClass"); } </code></pre> <p>The code is now working, sory for the trouble, Thank you all.

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).
