Picker Svelte Component

There is no specific Picker Svelte component, you need to use core Picker component.

Examples

picker.svelte
<script>
  import { f7, Navbar, Page, Block, BlockTitle, List, ListInput } from 'framework7-svelte';

  let pickerDevice;
  let pickerDescribe;
  let pickerDependent;
  let pickerCustomToolbar;
  // eslint-disable-next-line
  let pickerInline;

  function onPageInit() {
    const today = new Date();
    // iOS Device picker

    <p>
      Picker is a powerful component that allows you to create custom overlay pickers which looks
      like native picker.
    </p>
    <p>
      Picker could be used as inline component or as overlay. Overlay Picker will be automatically
      converted to Popover on tablets (iPad).
