# Filter Rows (Premium)
## Buttons
**Step 1:**
Click on the grey gear icon to access the Button Settings (on the button, that you want to filter with). You can also use images, or any other element to trigger the filtering. It doesn’t have to be a button module.
**Step 2:**
Go to Advanced → CSS ID & Classes → CSS Class. Here you add the **df-button** class.
**Step 3:**
Additionally add any category that you want to filter with that button like that: **dfc-\[your category]** e.g. dfc-cats.
{% hint style="info" %}
Buttons have to be in a separate section, than your filterable elements. Or you add the df-buttons class to your button row (Premium features).
{% endhint %}
## Section
**Step 1:**
Click on blue gear icon to access the Section Settings.
**Step 2:**
Go to Advanced → CSS ID & Classes → CSS Class. Here you add the **df-area** and **df-rows** class.
So you add: df-area df-rows
## Row
**Step 1:**
Click on green gear icon to access the Row Settings.
**Step 2:**
Go to Advanced → CSS ID & Classes → CSS Class.
Here you add all the **dfc-\[your category]** class you want, e.g. your dfc-cats class.
**Step 3:**
Do that for all rows you want to filter.
