# Template Examples

### Using variable paths that contain spaces in their names

Let’s assume a brick produces an output called `@userPreferences` and you want to reference the `favorite color` in a text template.

In the Page Editor Data Panel, the Output Data Tab might show:

Example Output Tab of the Data Panel showing data with names that include spaces.

To use the favorite color in a text template expression, **you must use square brackets and quotation marks**:

```
Your favorite color is {{ @userPreference.data["favorite color"] }}
```

### Text substitution using the replace filter

To replace all occurrences of a word or phrase, use the `replace` filter. For example, to replace all occurrences of `bricks` with `brix`:

```
{{ @description | replace("bricks", "brix") }}
```

### Chaining multiple filters in an expression

You can chain multiple filters using the `|` pipe operator. For example:

```
{{ "Lorem ipsum dolor sit amet" | truncate(15) | title }}
```

Will produce the following text output:

```
Lorem Ipsum...
```

### Looping over elements of an array

You can use the [for tag](https://mozilla.github.io/nunjucks/templating.html#for) to loop over elements of an array. This is handy for creating bulleted lists in inputs that support Markdown, such as the [Render Markdown brick](https://www.pixiebrix.com/marketplace/520b2dc6-11a9-4a9c-9753-58e3f2ed4513/render-markdown/)

```
{% for @item in @items %}
- {{ @item }}
{% endfor %}
```
