# Basics

{% hint style="info" %}
The `filter` block allows you to filter a query directly on the front end using different parameters.
{% endhint %}

{% hint style="danger" %}
The `filter` block will only work with a `query`block that has the front end rendering property toggled on.
{% endhint %}

The `filter` block is able to filter anything inside a `query` block.

The `filter` block is usually inserted into a parent block.
