Angular component providing an input field for searching / filtering MatSelect options of the Angular Material library.
See it in action at https://stackblitz.com/github/bithost-gmbh/ngx-mat-select-search-example
Important Note: This project is meant as a temporary implementation of angular/components#5697. The goal is to have an implementation in the official Angular Material repository, once angular/components#7835 is merged.
Install ngx-mat-select-search
in your project:
npm install ngx-mat-select-search
Import the NgxMatSelectSearchModule
in your app.module.ts
:
import { MatFormFieldModule, MatSelectModule } from '@angular/material';
import { NgxMatSelectSearchModule } from 'ngx-mat-select-search';
@NgModule({
imports: [
ReactiveFormsModule,
BrowserAnimationsModule,
MatSelectModule,
MatFormFieldModule,
NgxMatSelectSearchModule
],
})
export class AppModule {}
Use the ngx-mat-select-search
component inside a mat-select
element by placing it inside a <mat-option>
element:
<mat-form-field>
<mat-select [formControl]="bankCtrl" placeholder="Bank" #singleSelect>
<mat-option>
<ngx-mat-select-search [formControl]="bankFilterCtrl"></ngx-mat-select-search>
</mat-option>
<mat-option *ngFor="let bank of filteredBanks | async" [value]="bank">
{{bank.name}}
</mat-option>
</mat-select>
</mat-form-field>
See the example in https://github.com/bithost-gmbh/ngx-mat-select-search/blob/master/src/app/app.component.html
and https://github.com/bithost-gmbh/ngx-mat-select-search/blob/master/src/app/app.component.ts
how to wire the ngx-mat-select-search
and filter the options available.
Or have a look at https://github.com/bithost-gmbh/ngx-mat-select-search-example to see it in a standalone app.
You can alternatively use it with template driven forms as follows:
<ngx-mat-select-search ngModel (ngModelChange)="filterMyOptions($event)">
In order to change the labels, use the inputs specified in the API section as follows:
<ngx-mat-select-search [formControl]="bankFilterCtrl"
placeholderLabel="Find bank..."
noEntriesFoundLabel="'no matching bank found'"></ngx-mat-select-search>
To use the i18n API for translation of the labels, add the corresponding i18n-...
attributes:
<ngx-mat-select-search [formControl]="bankFilterCtrl"
placeholderLabel="Find bank..."
i18n-placeholderLabel
noEntriesFoundLabel="'no matching bank found'"
i18n-noEntriesFoundLabel></ngx-mat-select-search>

The MatSelectSearchComponent
implements the ControlValueAccessor interface.
Furthermore, it provides the following inputs:
/** Label of the search placeholder */
@Input() placeholderLabel = 'Suche';
/** Type of the search input field */
@Input() type = 'text';
/** Label to be shown when no entries are found. Set to null if no message should be shown. */
@Input() noEntriesFoundLabel = 'Keine Optionen gefunden';
/**
* Whether or not the search field should be cleared after the dropdown menu is closed.
* Useful for server-side filtering. See [#3](https://github.com/bithost-gmbh/ngx-mat-select-search/issues/3)
*/
@Input() clearSearchInput = true;
/** Whether to show the search-in-progress indicator */
@Input() searching = false;
/** Disables initial focusing of the input field */
@Input() disableInitialFocus = false;
/** Enable clear input on escape pressed */
@Input() enableClearOnEscapePressed = false;
/**
* Prevents home / end key being propagated to mat-select,
* allowing to move the cursor within the search input instead of navigating the options
*/
@Input() preventHomeEndKeyPropagation = false;
/** Disables scrolling to active options when option list changes. Useful for server-side search */
@Input() disableScrollToActiveOnOptionsChanged = false;
/** Adds 508 screen reader support for search box */
@Input() ariaLabel = 'dropdown search';
/** Whether to show Select All Checkbox (for mat-select[multi=true]) */
@Input() showToggleAllCheckbox = false;
/** select all checkbox checked state */
@Input() toggleAllCheckboxChecked = false;
/** select all checkbox indeterminate state */
@Input() toggleAllCheckboxIndeterminate = false;
/** Display a message in a tooltip on the toggle-all checkbox */
@Input() toggleAllCheckboxTooltipMessage = '';
/** Define the position of the tooltip on the toggle-all checkbox. */
@Input() toogleAllCheckboxTooltipPosition: 'left' | 'right' | 'above' | 'below' | 'before' | 'after' = 'below';
/** Show/Hide the search clear button of the search input */
@Input() hideClearSearchButton = false;
/**
* Text that is appended to the currently active item label announced by screen readers, informing the user of the current index, value and total
* options.
* eg: Bank R (Germany) 1 of 6
*/
@Input() indexAndLengthScreenReaderText = ' of ';
/** Output emitter to send to parent component with the toggle all boolean */
@Output() toggleAll = new EventEmitter<boolean>();
In order to customize the search icon, add the ngxMatSelectSearchClear
to your custom clear item (a mat-icon
or any other element) and place it inside the ngx-mat-select-search
component:
<ngx-mat-select-search>
<mat-icon ngxMatSelectSearchClear>delete</mat-icon>
</ngx-mat-select-search>
Custom content with the CSS class mat-select-search-custom-header-content
can be transcluded as follows:
<ngx-mat-select-search>
<div class="mat-select-search-custom-header-content">something special</div>
</ngx-mat-select-search>
- The currently selected option might be hidden under the search input field when opening the options panel and the panel is at the screen border.
We aim at providing the best service possible by constantly improving NgxMatSelectSearch
and responding fast to bug reports. We do this fully free of cost.
