title: collections.Dictionary
description: Creates a map from a list of key and value pairs.
categories: []
keywords: []
action:
aliases: [dict]
related:
- functions/collections/Slice
returnType: mapany
signatures: ['collections.Dictionary KEY VALUE [VALUE...]']
aliases: [/functions/dict]
---
```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:
### Partial definition
{{< code file=layouts/partials/svgs/external-links.svg >}}

{{< /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 >}}
[partials]: /templates/partials/
