# Fixed class

When the filtering is activated in Elementor Filter all classes applied to your rows or columns are removed and moved with the element.

If you would like certain classes to stay, then you can use the prefix **`efs-[classname]`**.

This is useful, for example, if you are building asymmetrical grid layouts, and you need to preserve the look of your grid when you filter.
