Usage

To use the PickerField in markup you need to:

If you are developing a NativeScript Core app, you need to register the plugin namespace in the xml:

<Page
   xmlns="http://schemas.nativescript.org/tns.xsd"
   xmlns:picker="@nativescript/picker">
   <picker:PickerField hint="Click here" items="{{ pickerItems }}"/>
...

If you are developing a NativeScript Angular app, you need to import the plugin module in the module of your component:

import { NativeScriptPickerModule } from "@nativescript/picker/angular";
...
@NgModule({
    imports: [
        NativeScriptPickerModule,
        ...
    ],
    ...

Then you will be able to declare the fields in the html of your component:

<PickerField hint="Click here" [items]="pickerItems"></PickerField>

If you are developing a NativeScript Vue app, you need to install the plugin in you app.js file:

import Vue from 'nativescript-vue';
import { PickerField } from '@nativescript/picker/vue';

Vue.use(PickerField);

Then you will be able to declare the fields in the template of your component:

<PickerField hint="Click here"></PickerField>

Features

PickerField

The PickerField is a NativeScript TextField which means that any functionality the default TextField provides is also available in the PickerField component. The only difference is that by design it is in "read-only" mode, or simply put you cannot change its text by input or select that text. Changing the text of the PickerField is done by its main functionality which is opening a modal popup that shows a list of objects from which you can select one by tapping it.

The PickerField also opens a modal window containing a Page element that contains an ActionBar and a ListView.
