About

Derived from angular-text-input-autocomplete 0.1.2:

https://www.npmjs.com/package/angular-text-input-autocomplete

All configuration is same as angular-text-input-autocomplete.

Some changes:

• Background color for catalog name, which is identified by '---'. Meaning, any item in the dropdown list starts with '---' will have a different background.
• Escape key closes the dropdown menu
• Dropdown menu is scrollable
• Up/Down arrows scroll the scrollable dropdown menu.

Installation

Install through npm:

npm install --save ngx-input-autocomplete

For older browsers you will need the keyboardevent-key-polyfill polyfill:

npm install --save keyboardevent-key-polyfill

Then include in your apps module:

import { polyfill as keyboardEventKeyPolyfill } from 'keyboardevent-key-polyfill';
import { NgModule } from '@angular/core';
import { TextInputAutocompleteModule } from 'ngx-input-autocomplete';
 
keyboardEventKeyPolyfill();
 
@NgModule({
  imports: [
    TextInputAutocompleteModule
  ]
})
export class MyModule {}

Finally use in one of your apps components:

import { Component } from '@angular/core';
 
@Component({
  selector: 'mwl-demo-app',
  template: `
    <mwl-text-input-autocomplete-container>
      <textarea
        placeholder="Type @ to search..."
        class="form-control"
        rows="5"
        [(ngModel)]="formControlValue"
        mwlTextInputAutocomplete
        [findChoices]="findChoices"
        [getChoiceLabel]="getChoiceLabel">
      </textarea>
    </mwl-text-input-autocomplete-container>
  `
})
export class DemoComponent {
  formControlValue = '';
 
  findChoices(searchText: string) {
    return ['John', 'Jane', 'Jonny'].filter(item => item.toLowerCase().includes(searchText.toLowerCase()));
  }
 
  getChoiceLabel(choice: string) {
    return `@${choice} `;
  }
}
