# Filter

Variables can be modified by filters. Filters are separated from the variable name by a pipe symbol |. Multiple filters can be chained. The output of one filter is applied to the next.

The following example removes all HTML tags from the name and title-cases it:

{{ name  |title }}

Filters that accept arguments have parentheses around the arguments. This example joins the elements of a list with commas:

{{ list | join(', ') }}

To apply a filter on a section of code, wrap it with the filter tag:

{% filter lower | title %}
{% endfilter %}}
