Input Tel Dropdown: Use Cases: Lion

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