Input Tel Dropdown

When .allowedRegions is not configured, all regions/countries will be available in the dropdown list. Once a region is chosen, its country/dial code will be adjusted with that of the new locale.

export const InputTelDropdown = () => html`
  <lion-input-tel-dropdown
    label="Select region via dropdown"
    help-text="Shows all regions by default"
    name="phoneNumber"
  ></lion-input-tel-dropdown>
  <h-output
    .show="${['modelValue', 'activeRegion']}"
    .readyPromise="${PhoneUtilManager.loadComplete}"
  ></h-output>
`;

Allowed regions

When .allowedRegions is configured, only those regions/countries will be available in the dropdown list.

export const allowedRegions = () => html`
  <lion-input-tel-dropdown
    label="Select region via dropdown"
    help-text="With region code 'NL'"
    .modelValue=${'+31612345678'}
    name="phoneNumber"
    .allowedRegions=${['NL', 'DE', 'GB']}
  ></lion-input-tel-dropdown>
  <h-output
    .show="${['modelValue', 'activeRegion']}"
    .readyPromise="${PhoneUtilManager.loadComplete}"
  ></h-output>
`;

Preferred regions

When .preferredRegions is configured, they will show up on top of the dropdown list to enhance user experience.

export const preferredRegionCodes = () => html`
  <lion-input-tel-dropdown
    label="Select region via dropdown"
    help-text="Preferred regions show on top"
    .modelValue=${'+31612345678'}
    name="phoneNumber"
    .allowedRegions=${['NL', 'DE', 'GB', 'BE', 'US', 'CA']}
    .preferredRegions=${['NL', 'DE']}
  ></lion-input-tel-dropdown>
  <h-output
