    <p>I think you need to also keep track of the order the elements were clicked. I would suggest you do this by keeping an object that will act as a sort of key/value pair, where the key is the "id" of the element clicking/unclicking, and the value is the number it was clicked (i.e. 1 = red, 2 = green, etc.). </p> <p>Then, in changeClass(), when adding the class, you can also add to the object the number it was clicked at. When removing the class, you can unset the key in the object and iterate over the items in the object and decrement anything that had a higher value. This decrement will allow you to adjust the color/number of anything that was clicked after that button that was just "unclicked" (e.g. a blue button should turn green if you "unclick" the green button).</p> <p>Might look something like this:</p> <p>Initialize with this:</p> <pre><code>var state = {}; </code></pre> <p>Do this when clicking (before incrementing nextclass):</p> <pre><code>state[element.id] = nextClass; </code></pre> <p>Do this when unclicking:</p> <pre><code>var removedNum = state[element.id]; delete state[element.id]; nextClass--; if (nextClass &lt; 0) { nextClass += classes.length; } var i; var keys = Object.keys(state); for (i = 0; i &lt; keys.length; i++) { if (state[keys[i]] &gt;= removedNum) { // decrement only things after the button unclicked var checkElement = document.getElementById(keys[i]); state[keys[i]]--; var checkClass = hasClass(checkElement, classes); if (checkClass) { // remove its existing class checkElement.classList.remove(checkClass); } // add the one it should now have checkElement.classList.add( classes[state[keys[i]]] ); } } </code></pre>

    3. COOh Yeah, So I ended up figuring it out a different way and I'll post the code if you care to look. I really like your way of doing this though, it has opened up new ideas on how I can overcome different problems. Never really looked at using objects in that manner. Always been stuck with the basics; conditional, loop and variables. I'm pretty new to JavaScript though. Thank you again and if you get a chance look at my code and let me know what you think.

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).
