-<!--
-Material design: [Chips](https://material.io/guidelines/components/chips.html#).
-
-> A chip web component made with Polymer 2 following Material Design guidelines
-
-Polymer 2.x `<paper-chip>` may contain a icon or a photo, some line of text or a contact information with Material Design styling.
-
-## Usage
-
-Basic paper-chip.
-
-```html
-<paper-chip single-line>
-    <div slot="label" class="label">Single-line Chip</div>
-</paper-chip>
-```
-
-It can show **single-line** or **multi-line** text. You can open a multi-line chip tapping on it.
-
-```html
-<paper-chip>
-    <iron-icon slot="icon" class="icon" icon="avatars:avatar-1"></iron-icon>
-    <div slot="label" class="label">John Foo</div>
-    <div slot="caption" class="caption">jfoo@doh.com</div>
-</paper-chip>
-```
-
-Configure some basic behavior. It may be removable or not.
-
-```html
-<paper-chip removable>
-    <div slot="label" class="label">Removable Chip</div>
-</paper-chip>
-```
-
-Choose to set animation in openable chip.
-
-```html
-<paper-chip removable animated>
-    <div slot="icon" class="icon">P</div>
-    <div slot="label" class="label">John Foo</div>
-    <div slot="caption" class="caption">jfoo@doh.com</div>
-</paper-chip>
-```
-
-Use `<paper-chip-input>` component to collect a set of `chip`.
-
-```html
-    <paper-chip-input></paper-chip-input>
-```
-
-Do you want to change the **keys** that automatically submit chips?
-
-No worries, we support it!
-
-Configure them with the `enter-keys` property adding the keys.
-
-We support the [Polymer.IronA11yKeysBehavior](https://github.com/PolymerElements/iron-a11y-keys-behavior) format.
-
-Following example should clarify the usage of this feature.
-
-```html
-<paper-chip-input enter-keys='["enter", "space"]'></paper-chip-input>
-```
-
-
-Do you need **autocomplete** ?
-
-When you have a predefined and finite set of input values you can set the predefined values with `datasource` property.
-
-```html
-<paper-chip-input label="Weekdays" datasource='[{"value": "1", "label": "monday" },{"value": "2", "label": "tuesday"}, {"value": "3", "label": "wednesday"}, {"value": "4", "label": "thursday"}, {"value": "5", "label": "friday"}, {"value": "6", "label": "saturday"}, {"value": "7", "label": "sunday"}]'  placeholder="Add day"></paper-chip-input>
-```
-
-The default properties for datasource are `label` and `value`, but you can configure it from outside by the properties `display-property` and `value-property`.
-
-```html
-<paper-chip-input display-property="value" value-property="key">
-</paper-chip-input>
-```
-
-```json
-{ "value": "apple", "key": 0 },
-{ "value": "apricot", "key": 1 }

-
-Autocomplete uses a **startWith** filter as default logic.
-
-Do you need to implement a **custom filter logic**? You can do it!
-
-Set `filter` property with your custom *function*. The following lines of code will show you how to do it.
-
-```html
-<paper-chip-input id="weekdays" label="Weekdays" datasource='[{"value": "1", "label": "monday" },{"value": "2", "label": "tuesday"}, {"value": "3", "label": "wednesday"}, {"value": "4", "label": "thursday"}, {"value": "5", "label": "friday"}, {"value": "6", "label": "saturday"}, {"value": "7", "label": "sunday"}]' placeholder="Add day"></paper-chip-input>
-<script>
-let weekdays = document.querySelector("#weekdays")
-weekdays.filter = (data, value) => {
-    return data.filter((item) => item[weekdays.displayProperty].toLowerCase().includes(value.toLowerCase()))
-}
-</script>
-```
-
-## Styling
-
-The following custom properties and mixins are available for styling:
-
-Custom property | Description | Default
-----------------|-------------|----------
-`--paper-chip-secondary-text-color` | The paper-chip label-color |
-`--paper-chip-background-color` | The paper-chip background-color |
-`--paper-chip-icon-background-color` | The paper-chip avatar background-color |
-`--paper-chip-icon-text-color` | The paper-chip icon color |
-`--paper-chip-closed-label-max-width` | The paper-chip label max-width when is closed | 80px
-
-## Testing
-If you are using **polyserve** navigate to the `test/` directory of your element to run its tests. You can view results in browser console.
-
-### web-component-tester
-
-The tests are compatible with [web-component-tester](https://github.com/Polymer/web-component-tester).
-
-Install it via:
-
-```sh
-npm install web-component-tester
-```
-
-The `wct` tool will run your tests in all the browsers you have installed. Just
-run it:
-
-```sh
-wct
-```
-
-By default, any tests under `test/` will be run. You can override this by
-specifying particular files (or globs of files) via `wct path/to/files`.
-
-Otherwise you can run the test suite via npm script
-
-```sh
-npm test
-```

+/**
+ * Material design: [Chips](https://material.io/guidelines/components/chips.html#).
+ *
+ *  > A chip web component made with Polymer 2 following Material Design guidelines
+ *
+ *  Polymer 2.x `<paper-chip>` may contain a icon or a photo, some line of text or a contact information with Material Design styling.
+ *
+ *  ## Usage
+ *
+ *  Basic paper-chip.
+ *
+ *  ```html
+ * <paper-chip single-line>
+ *     <div slot="label" class="label">Single-line Chip</div>
+ * </paper-chip>
+ * ```
+ *
+ *  It can show **single-line** or **multi-line** text. You can open a multi-line chip tapping on it.
+ *
+ *  ```html
+ * <paper-chip>
+ *     <iron-icon slot="icon" class="icon" icon="avatars:avatar-1"></iron-icon>
+ *     <div slot="label" class="label">John Foo</div>
+ *     <div slot="caption" class="caption">jfoo@doh.com</div>
+ * </paper-chip>
+ * ```
+ *
+ *  Configure some basic behavior. It may be removable or not.
+ *
+ *  ```html
+ * <paper-chip removable>
+ *     <div slot="label" class="label">Removable Chip</div>
+ * </paper-chip>
+ * ```
+ *
+ *  Choose to set animation in openable chip.
+ *
+ *  ```html
+ * <paper-chip removable animated>
+ *     <div slot="icon" class="icon">P</div>
+ *     <div slot="label" class="label">John Foo</div>
+ *     <div slot="caption" class="caption">jfoo@doh.com</div>
+ * </paper-chip>
+ * ```
+ *
+ *  Use `<paper-chip-input>` component to collect a set of `chip`.
+ *
+ *  ```html
+ *     <paper-chip-input></paper-chip-input>
+ * ```
+ *
+ *  Do you want to change the **keys** that automatically submit chips?
+ *
+ *  No worries, we support it!
+ *
+ *  Configure them with the `enter-keys` property adding the keys.
+ *
+ *  We support the [Polymer.IronA11yKeysBehavior](https://github.com/PolymerElements/iron-a11y-keys-behavior) format.
+ *
+ *  Following example should clarify the usage of this feature.
+ *
+ *  ```html
+ * <paper-chip-input enter-keys='["enter", "space"]'></paper-chip-input>
+ * ```
+ *
+ *
+ *  Do you need **autocomplete** ?
+ *
+ *  When you have a predefined and finite set of input values you can set the predefined values with `datasource` property.
+ *
+ *  ```html
+ * <paper-chip-input label="Weekdays" datasource='[{"value": "1", "label": "monday" },{"value": "2", "label": "tuesday"}, {"value": "3", "label": "wednesday"}, {"value": "4", "label": "thursday"}, {"value": "5", "label": "friday"}, {"value": "6", "label": "saturday"}, {"value": "7", "label": "sunday"}]'  placeholder="Add day"></paper-chip-input>
+ * ```
+ *
+ *  The default properties for datasource are `label` and `value`, but you can configure it from outside by the properties `display-property` and `value-property`.
+ *
+ *  ```html
+ * <paper-chip-input display-property="value" value-property="key">
+ * </paper-chip-input>
+ * ```
+ *
+ *  ```json
+ * { "value": "apple", "key": 0 },
+ * { "value": "apricot", "key": 1 }
+ * ```
+ *
+ *  Autocomplete uses a **startWith** filter as default logic.
+ *
+ *  Do you need to implement a **custom filter logic**? You can do it!
+ *
+ *  Set `filter` property with your custom *function*. The following lines of code will show you how to do it.
+ *
+ *  ```html
+ * <paper-chip-input id="weekdays" label="Weekdays" datasource='[{"value": "1", "label": "monday" },{"value": "2", "label": "tuesday"}, {"value": "3", "label": "wednesday"}, {"value": "4", "label": "thursday"}, {"value": "5", "label": "friday"}, {"value": "6", "label": "saturday"}, {"value": "7", "label": "sunday"}]' placeholder="Add day"></paper-chip-input>
+ * <script>
+ * let weekdays = document.querySelector("#weekdays")
+ * weekdays.filter = (data, value) => {
+ *     return data.filter((item) => item[weekdays.displayProperty].toLowerCase().includes(value.toLowerCase()))
+ * }
+ * </script>
+ * ```
+ *
+ *  ## Styling
+ *
+ *  The following custom properties and mixins are available for styling:
+ *
+ *  Custom property | Description | Default
+ * ----------------|-------------|----------
+ * `--paper-chip-secondary-text-color` | The paper-chip label-color |
+ * `--paper-chip-background-color` | The paper-chip background-color |
+ * `--paper-chip-icon-background-color` | The paper-chip avatar background-color |
+ * `--paper-chip-icon-text-color` | The paper-chip icon color |
+ * `--paper-chip-closed-label-max-width` | The paper-chip label max-width when is closed | 80px
+ *
+ *  ## Testing
+ * If you are using **polyserve** navigate to the `test/` directory of your element to run its tests. You can view results in browser console.
+ *
+ *  ### web-component-tester
+ *
+ *  The tests are compatible with [web-component-tester](https://github.com/Polymer/web-component-tester).
+ *
+ *  Install it via:
+ *
+ *  ```sh
+ * npm install web-component-tester
+ * ```
+ *
+ *  The `wct` tool will run your tests in all the browsers you have installed. Just
+ * run it:
+ *
+ *  ```sh
+ * wct
+ * ```
+ *
+ *  By default, any tests under `test/` will be run. You can override this by
+ * specifying particular files (or globs of files) via `wct path/to/files`.
+ *
+ *  Otherwise you can run the test suite via npm script
+ *
+ *  ```sh
+ * npm test
+ * ```
