# Filter already applied (Premium)

## By Starting Class

If you want to have your elements already filtered, after the page load you add a **`efc-[your category]`** class to the `ef-area` **section**.

There must be a button with the same `efc-` class.

So if you want to start the filtering with `efc-cats`. You have to have a button with a `efc-cats` class.

## By URL

You can also determine what filter is applied with the URL. For example:

<https://demos.danielvoelk.de/ice-cream/?filter=stick>

<https://demos.danielvoelk.de/ice-cream/?filter=cone>

You have to just add `?filter=CATEGORY` and the category without `efc-`
