# Pill

Pills are decorative elements that display information about content they attach to. They can be links to other content or simple colored labels.

You can add text to pills by adding it between the `<Pill>` tags. Alternatively, you can set `v-model` and [make the pill editable](#editable-pill).

| Prop    | Data type                                                                                       | Required? | Default     | Description            |

-> [Let the user create lists of pills](./pills)

### Primary

Primary pills convey **positive** information.

```vue-html
<Pill primary>
  Primary pill
</Pill>
```

<Pill primary>
  Primary pill
</Pill>

### Secondary

Secondary pills convey **neutral** or simple decorational information such as genre tags.

::: info
This is the default type for pills. If you don't specify a type, a **secondary** pill is rendered.
:::

```vue-html
<Pill>
  Secondary pill
</Pill>
```

<Pill>
  Secondary pill
</Pill>

### Destructive

Destructive pills convey **destructive** or **negative** information. Use these to indicate that information could cause issues such as data loss.

```vue-html
<Pill destructive>
  Destructive pill
</Pill>
```

<Pill destructive>
  Destructive pill
</Pill>

## Pill colors

## Image pill

Image pills contain a small circular image on their left. These can be used for decorative links such as artist links. To created an image pill, insert a link to the image between the pill tags as a `<template>`.

```vue-html{2-4}
<Pill>
  <template #image>
    <div style="background-color: #ff0" />
  </template>
  Awesome artist
</Pill>
```

<Pill>
  <template #image>
    <div style="background-color: #ff0" />
  </template>
  Awesome artist
</Pill>

### Reduce space between image/icon and text

```vue-html{5}
<Pill>
  <template #image>
    <div style="background-color: currentcolor; width: 8px; height: 8px; margin: 8px;" />
  </template>
  <span style="margin-left: -12px;">
    Awesome artist
  </span>
</Pill>
```

<Pill>
  <template #image>
    <div style="background-color: currentcolor; width: 8px; height: 8px; margin: 8px;" />
  </template>
  <span style="margin-left: -12px;">
    Awesome artist
  </span>
</Pill>

## Editable pill

Add `v-model="..."` to link the pill content to a `ref` with one `current` item and zero or more `others`. Set each item's `type` to `preset` or `custom`.

- The `current` item can be changed by the user.
- The `other` items can be selected instead of the `current`.
- Items with type `custom` can be edited and deleted by the user. `preset` items can only be selected or deselected.

```ts
import { ref } from "vue"
const current = ref({ type: 'custom', label: 'I-am-custom.-Change-me!' })
const others = ref([
    { type: 'preset', label: 'Preset-1' },
    { type: 'preset', label: 'Preset-2' },
    { type: 'preset', label: 'Preset-3' },
  ])
```

```vue-html
<Pill
  v-model:current="current"
  v-model:others="others"
/>
```

<Pill
  v-model:current="current"
  v-model:others="others"
/>

## Add an action

<Button primary ghost icon="bi-trash"/>

```vue-html
<Pill
  v-model:current="current"
  v-model:others="others"
>
  <template #action>
    <Button ghost primary round icon="bi-x"
      title="Deselect"
      @click.stop.prevent="() => {
        if (customTag.current.type === 'custom')
          customTag.others.push({...customTag.current});
        customTag.current = {label: '', type: 'custom'}
      }"
    />
  </template>
</Pill>
```

<!-- prettier-ignore-start -->

<Pill
  v-model:current="current"
  v-model:others="others"
>
  <template #action>
    <Button ghost primary round icon="bi-x"
      title="Deselect"
      @click.stop.prevent="() => {
        if (current.type === 'custom')
          others.push({...current});
        current = {label: '', type: 'custom'}
      }"
    />
  </template>
</Pill>

{{ current }} (+ {{ others.length }} other options)
