I’m using jquery-plugin columnizer
http://welcome.totheinter.net/columnizer-jquery-plugin/
It is sometimes very slow to create the columns (you can try changing the browser window size, or selecting a filter.
Sometimes Firefox gives the error message: “Unresponsive Javascript script” and I have to press on continue to continue the navigation.
thanks
I’ve solved by compressing and compacting the js files. Now the performance is good. Check Google page speed.
