given front matter with an array as such

```auto
+++
[extra]
features = [
        {name="Weight", value="1.12 kg"},
        {name="Dimensions", value="4 x 8 m"},
]

```

is it possible to select one matching a selector along the lines of

`page.extra.features[name='Weight']`

Possibly a bit verbose but maybe something like this? If I understood correctly.

```auto
{% for feature in page.extra.features %}
    {% if feature.name is matching("Weight") %}
        {{ feature.name }}
    {% endif %}
{% endfor %}

```

Yes, i’m currently doing that. It’s nasty.  
I was hoping some short cut existed for accessing objects.

its possible to access a value using the key

{`{ page.extra['title'] }}`

and also possible to access an object (not within an array) given

```auto
+++
[extra]
weight = {unit="kg", value=1.2}

```

both forms access the object in the template

```auto
{{ page.extra.weight.value }} {{ page.extra.weight.unit }}
{{ page.extra.weight['value'] }} {{ page.extra.weight['unit'] }}

```

but not for accessing an object WITHIN an array.

```auto
+++
[extra]
features = [
        {name="Weight", value="1.12 kg"},
        {name="Dimensions", value="4 x 8 m"},
]

```

ill try the some tera ‘built-ins’

The tera [filter](https://keats.github.io/tera/docs/#filter) looks promising

```auto
page.extra.feature | filter(attribute='name', value="Weight")}}

```

Looks like it returns an array of object. Now to access the first element in the array.

```auto
{% set x = page.extra.feature | filter(attribute='name', value="Weight") | first %}
{{x}}

```

Would like to access that in one line but this is a good start
