RadAutoCompleteTextView Display Modes

RadAutoCompleteTextView has two predefined display modes.

Display mode can be changed with the displayMode property of the RadAutoCompleteTextView. The default value is Plain.

The next code snippet shows how to change that default value to Tokens:

<RadAutoCompleteTextView [items]="dataItems" displayMode="Tokens" showCloseButton="false">
    <SuggestionView tkAutoCompleteSuggestionView suggestionViewHeight="300">
        <ng-template tkSuggestionItemTemplate let-item="item">
            <StackLayout orientation="vertical" padding="10">
                <Label [text]="item.text"></Label>
            </StackLayout>
        </ng-template>
    </SuggestionView>
</RadAutoCompleteTextView>

import { Component } from "@angular/core";
import { ObservableArray } from "tns-core-modules/data/observable-array";
import { TokenModel } from "nativescript-ui-autocomplete";

@Component({
    moduleId: module.id,
    selector: "tk-autocomplete-tokens-mode",
    templateUrl: "autocomplete-tokens-mode.component.html"
})
export class AutoCompleteTokensModeComponent {
    private _items: ObservableArray<TokenModel>;
    private countries = ["Australia", "Albania", "Austria", "Argentina", "Maldives", "Bulgaria", "Belgium", "Cyprus", "Italy", "Japan",
        "Denmark", "Finland", "France", "Germany", "Greece", "Hungary", "Ireland",
        "Latvia", "Luxembourg", "Macedonia", "Moldova", "Monaco", "Netherlands", "Norway",
        "Poland", "Romania", "Russia", "Sweden", "Slovenia", "Slovakia", "Turkey", "Ukraine",
        "Vatican City", "Chad", "China", "Chile"];

    constructor() {
        this.initDataItems();
    }

    get dataItems(): ObservableArray<TokenModel> {
        return this._items;
    }

    private initDataItems() {
        this._items = new ObservableArray<TokenModel>();

        for (let i = 0; i < this.countries.length; i++) {
            this._items.push(new TokenModel(this.countries[i], undefined));
        }
    }
}

Plain mode

In plain mode the RadAutoCompleteTextView displays chosen item as plain text. With this mode only one item can be chosen.

Tokens mode

Tokens mode allows multiple choice of items, which are displayed as tokens.

When RadAutoCompleteTextView's displayMode is Tokens, you can apply two different behaviors for token arrangement.

The layout mode of the tokens can be changed with the layoutMode property. The default value of this property is Wrap.

<RadAutoCompleteTextView #autocomplete [items]="dataItems" layoutMode="Wrap" displayMode="Tokens">
    <SuggestionView tkAutoCompleteSuggestionView suggestionViewHeight="300">
        <ng-template tkSuggestionItemTemplate let-item="item">
            <StackLayout orientation="vertical" padding="10">
                <Label [text]="item.text"></Label>
            </StackLayout>
        </ng-template>
    </SuggestionView>
</RadAutoCompleteTextView>

import { Component, ViewChild } from "@angular/core";
import { ObservableArray } from "tns-core-modules/data/observable-array";
import { TokenModel } from "nativescript-ui-autocomplete";
import { RadAutoCompleteTextViewComponent } from "nativescript-ui-autocomplete/angular";

@Component({
    moduleId: module.id,
    selector: "tk-autocomplete-layouts-wrap",
    templateUrl: "autocomplete-layouts-wrap.component.html"
})
export class AutoCompleteLayoutsWrapComponent {
    private _items: ObservableArray<TokenModel>;
    private countries = ["Australia", "Albania", "Austria", "Argentina", "Maldives", "Bulgaria", "Belgium", "Cyprus", "Italy", "Japan",
        "Denmark", "Finland", "France", "Germany", "Greece", "Hungary", "Ireland",
        "Latvia", "Luxembourg", "Macedonia", "Moldova", "Monaco", "Netherlands", "Norway",
        "Poland", "Romania", "Russia", "Sweden", "Slovenia", "Slovakia", "Turkey", "Ukraine",
        "Vatican City", "Chad", "China", "Chile"];
    private lastIndex: number = 0;

    constructor() {
        this.initDataItems();
    }

    @ViewChild("autocomplete", { static: false }) autocomplete: RadAutoCompleteTextViewComponent;

    get dataItems(): ObservableArray<TokenModel> {
        return this._items;
    }

    private initDataItems() {
        this._items = new ObservableArray<TokenModel>();

        for (let i = 0; i < this.countries.length; i++) {
            this._items.push(new TokenModel(this.countries[i], undefined));
        }
    }

    public onAddToken(args) {
        if (this.dataItems.length <= this.lastIndex) {
            this.lastIndex = 0;
        }

        this.autocomplete.autoCompleteTextView.addToken(this._items.getItem(this.lastIndex));
        this.lastIndex++;
    }
}

Wrap Layout

In wrap mode tokens are arranged on multiple lines. Every time a new line is started the RadAutoCompleteTextView is expanding in order to show all tokens.

Horizontal Layout

In horizontal mode tokens are displayed on single line which can be scrolled horizontally in order to display all tokens.
