```go-html-template
{{ $m := dict "a" 1 "b" 2 }}
```

The above produces this data structure:

```json
{
  "a": 1,
  "b": 2
}
```


Note that the `key` can be either a `string` or a `string slice`. The latter is useful to create a deeply nested structure, e.g.:

```go-html-template
{{ $m := dict (slice "a" "b" "c") "value" }}
```

The above produces this data structure:

```json
{
  "a": {
    "b": {
      "c": "value"
    }
  }
}
```

## Pass values to a partial template

The partial below creates an SVG and expects `fill`, `height` and `width` from the caller:

{{< /code >}}

### Partial call

The `fill`, `height` and `width` values can be stored in one object with `dict` and passed to the partial:

{{< code file=layouts/_default/list.html >}}
{{ partial "svgs/external-links.svg" (dict "fill" "#01589B" "width" 10 "height" 20 ) }}
{{< /code >}}
