```js script
import { html } from '@lion/core';
import './src/md-combobox/md-combobox.js';
import './src/gh-combobox/gh-combobox.js';
import './src/wa-combobox/wa-combobox.js';
import './src/google-combobox/google-combobox.js';
```

Below several extensions can be found. They illustrate that complex UI components can be created
easily from an extended Lion component, just by:

- **configuring**: setting properties or providing conditions via methods
- **enhancing**: adding extra html/styles/logic without changing behavior of the extended element
- **overriding**: replace html/styles/logic of the extended element with your own

**Whatsapp example shows:**

export const GoogleSearch = () => {
  return html`
    <google-combobox name="combo" label="Google Search">

        >Beets</google-option
      >
    </google-combobox>
    <div style="height:200px;"></div>
  `;
};
```

**Google Search example shows:**

- advanced styling
- how to use options that are links
- create exact user experience of Google Search, by:
  - using autocomplete 'list' as a fundament (we don't want inline completion in textbox)
  - enhancing `_showOverlayCondition`: open on focus
  - enhancing `_syncToTextboxCondition`: always sync to textbox when navigating by keyboard (this needs to be enabled, since it's not provided in the "autocomplete=list" preset)
