# horizontal-kv-list
Provides a horizontally stacked list of key/value pairs, commonly used with a
definition/description list.
The keys can be configured to be either, visible, invisible, or with an icon.
- **Icon Configuration:** Add a `class` that describes the key/value pair and configure the icon for that class in the CSS
- **Visible Title Configuration:** Add an empty `class` attribute. A trailing `:`
will be added to the title (ensure you collapse the whitespace in the `dt`).
- **Invisible Title Configuration:** Don't add a `class` attribute at all, i.e. by default
the title is not shown.
If you are providing an icon, you should also use the `{{tooltip}}` modifier
to provide a textual tooltip for the icon. Using the `{{tooltip}}` modifier
with no arguments will make it use the text/DOM content of the DOM element it
is attached to, see below for a full usage example.
`<CopyButton />` components are commonly added to the value, and can be added
to the left or right of the value.

When conditionally listing key/values within a single `dl`, be aware that if no key/values should be shown, then you will be left with an empty `dl`. If you collapse the whitespace using handlebars whitespace collapsing `~`, then this empty `dl` will be removed from the flow via CSS. Alternatively consider using multiple `dl`s which can be wrapped with conditionals individually and therefore leave no empty DOM.
When using as individual `dl` lists be aware of whitespace between `dl`s. There are various ways you can counter this:
1. remove the whitespace `</dl><dl>`.
2. Wrap the whitespace in comments `</dl><!-- carriage return --><dl>`
3. Use handlebars whitespace removal `~` as above.
4. Put a `display: inline-flex` on the parent element (this can affect other layout).
Depending on your exact usecase one of the above options may be more suited than others.
```hbs preview-template
<figure>
<figcaption>
Conditionally showing multiple key/values sometimes means that you insert an empty `dl` into the DOM
</figcaption>
<dl>
{{~#if false}}
<dt>Something that might not be set</dt>
<dd>No value!</dd>
{{/if~}}
{{~#if false}}
<dt>Something that might not be set</dt>
<dd>No value!</dd>
{{/if~}}
</dl>
</figure>
```
