### HTML Embedded Widget
Many websites and apps provide their own embeddable widgets. These can be used with Dashy using the Embed widget, which lets you dynamically embed and HTML, CSS or JavaScript contents.
⚠️ **NOTE:** Use with extreme caution. Embedding a script from an untrustworthy source may have serious unintended consequences.
<p align="center"><img width="400" src="https://i.ibb.co/fkwNnxT/embed-widget-2.png" /></p>
##### Options
**Field** | **Type** | **Required** | **Description**
--- | --- | --- | ---
**`html`** | `string` | _Optional_ | HTML contents to render in the widget
**`script`** | `string` | _Optional_ | Raw JavaScript code to execute (caution)
**`scriptSrc`** | `string` | _Optional_ | A URL to JavaScript content (caution)
**`css`** | `string` | _Optional_ | Any stylings for widget contents
##### Example
```yaml
- type: embed
options:
scriptSrc: https://cdn.speedcheck.org/basic/scbjs.min.js
html: |
<div id="sc-container">
<div id="sc-branding" class="sc-bb">
<a target="_blank" href="https://www.speedcheck.org/">
<img src="https://cdn.speedcheck.org/branding/speedcheck-logo-18.png" alt="Speedcheck"/>
</a>
</div>
</div>
```
Or
```yaml
- type: embed
options:
css: '.coinmarketcap-currency-widget { color: var(--widget-text-color); }'
html: '<div class="coinmarketcap-currency-widget" data-currencyid="1" data-base="USD" data-secondary="" data-ticker="true" data-rank="true" data-marketcap="true" data-volume="true" data-statsticker="true" data-stats="USD"></div>'

<p align="center"><img width="700" src="https://i.ibb.co/1r88pvL/rss-feed-example-1.png" /></p>
##### Example

## Usage & Customizations
### Widget Usage Guide
Like items, widgets are placed under sections. You may have one or more widgets per section.
In your YAML config file, this will look something like:
```yaml
sections:
- name: Today
icon: far fa-calendar-day
widgets:
- type: clock
options:
format: en-GB
- type: weather
options:
apiKey: 6e29c7d514cf890f846d58178b6d418f
city: London
units: metric
```
> In this example, there is a single section, named "Today", using a Calendar icon from Font-Awesome. It has 2 widgets, a clock and the current weather.
---
### Continuous Updates
By default, a widget which displays dynamic data from an external source, will only fetch results on page load. If you would like to keep data updated at all times, you can enable **Continuous Updates**. This is done by setting a time value in the `updateInterval` field.
The value of `updateInterval` is optional, and is specified and seconds. It must be more than `10` and less than `7200`.
For example, the following widget displaying stats from Pi-Hole will update ever 20 seconds.
```yaml
widgets:
- type: pi-hole-stats
updateInterval: 20
options:
hostname: http://192.168.130.2
```
Note that if you have many widgets, and set them to continuously update frequently, you will notice a hit to performance. A widget that relies on data from an external API, will also consume your usage quota faster, if set to keep updating.
---
### Widget Styling
Like elsewhere in Dashy, all colours can be easily modified with CSS variables.
Widgets use the following color variables, which can be overridden if desired:
- `--widget-text-color` - Text color, defaults to `--primary`
- `--widget-background-color` - Background color, defaults to `--background-darker`
- `--widget-accent-color` - Accent color, defaults to `--background`
For more info on how to apply custom variables, see the [Theming Docs](/docs/theming.md#setting-custom-css-in-the-ui)
---
### Widget UI Options
Widgets can be opened in full-page view, by clicking the Arrow icon (top-right). The URL in your address bar will also update, and visiting that web address will take you straight to the selected widget.
You can reload the data of any widget, by clicking the Refresh Data icon (also in top-right). This will only affect the widget where the action was triggered from.
All [config options](/docs/configuring.md#section) that can be applied to sections, can also be applied to widget sections. For example, to make a widget span multiple columns, set `displayData.cols: 2` within the parent section. You can collapse a widget (by clicking the section title), and collapse state will be saved locally.
Widgets cannot currently be edited through the UI. This feature is in development, and will be released soon. In the meantime, you can either use the JSON config editor, or use VS Code or SSH into your box to edit the conf.yml file directly.

### Build your own Widget
Widgets are built in a modular fashion, making it easy for anyone to create their own custom components.
For a full tutorial on creating your own widget, you can follow [this guide](https://github.com/Lissy93/dashy/blob/master/docs/development-guides.md#building-a-widget), or take a look at [here](https://github.com/Lissy93/dashy/commit/3da76ce2999f57f76a97454c0276301e39957b8e) for a code example.
