Thumbnail grid with expanding preview and mini gallery

After being asked many times, via this tutorial and emails, how I created the LuxDeco Discover page I decided to finally create my own version of the Grid for you to download.

I’ll aim to keep this short because most people just want the answer and I don’t have too much time on my hands at the moment, hence the lack of posts.

I’ve got a working example here. You can also download the code from this link.

To show you what the structure of the new mini-gallery I drew at the image below. It may not be as clear as it could be but I think it’s a good rough outline.



I started off with editing a few bits of the Grid JavaScript first. I’ve included comments in the ‘grid.js’ file and I’ve pasted some key parts below. The changes start from line 341 in Grid.js:

What I’ve basically done it set up all elements and then appended them to the relative wrapping containers. I’ve then appended the wrapping containers to the large container. It’s written backwards as I need to ensure I’ve declared the to-be-appended items before appending them to any other elements.

The next step is to get all the data from the clicked image. This clicked image contains A LOT of data. It has our title, copy, href’s and our image paths.

At the end of the ‘update’ function we make a call to our Preview initiator function this.PreviewGallery();. This brings in our image gallery jQuery code. We have to call this in at this, last, point of the ‘update’ function to let jQuery find the DOM elements and bind our ‘onclick’ function.


For each grid item I’ve had to include some extra data-attributes. These hold the thumbnail paths as well as our URL’s.

Once you’ve edited the grid elements as needed you’ll need to fire it all up within the DOC READY function:

You can see it all in action here. You can also download the code from this link too!

Hope it’s of some use to you all! Please, ask questions, highlight issues, complain or provide some constructive feedback below – everything is welcome!
