# Filter already applied (Premium)

### By Starting Class <a href="#by-starting-class" id="by-starting-class"></a>

If you want to have your elements already filtered, after the page load you add a **`dfc-[your category]`** class to the `df-area` **section**.There must be a button with the same `dfc- class`.So if you want to start the filtering with `dfc-cats`. You have to have a button with a `dfc-cats` class.

### By URL <a href="#by-url" id="by-url"></a>

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 `dfc-`
