Having trouble with the Angular Material component? The element 'mat-option' is not recognized

I am having trouble with implementing an Angular Material component. The component is not functioning properly, and I received the following error message:

Uncaught Error: Template parse errors: 'mat-option' is not a known element:
// ...

I suspect that the issue lies within app.module.ts:

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { SidebarComponent } from './sidebar/sidebar.component';
import { PostsComponent } from './posts/posts.component';
import { UsersComponent } from './users/users.component';
import { DetailsComponent } from './details/details.component';
import { HttpClientModule } from '@angular/common/http';
import { FooterComponent } from './footer/footer.component'; 
import {MatButtonModule, MatCheckboxModule} from '@angular/material';
import {MatFormFieldModule} from '@angular/material/form-field';
import { MyFormComponent } from './my-form/my-form.component';
@NgModule({
  declarations: [
    AppComponent,
    SidebarComponent,
    PostsComponent,
    UsersComponent,
    DetailsComponent,
    FooterComponent, MyFormComponent
  ],
  imports: [
    BrowserModule, AppRoutingModule,HttpClientModule,MatButtonModule, MatCheckboxModule,MatFormFieldModule
  ]
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Answer №1

To properly use mat-option, you must include the MatSelectModule in your Angular project and import it into the AppModule.

import { ..., MatSelectModule, ... } from '@angular/material';

@NgModule({
   imports: [ ..., MatSelectModule, ...]
})
export class AppModule { }

Answer №2

Make sure to bring in the MatSelectModule,

imports: [
    BrowserModule,
    FormsModule,
    HttpModule,
    MaterialModule,
    MatSelectModule,
    //..Other modules here
],

Answer №3

It is important to remember to include both MatOptionModule and MatSelectModule in your imports.

imports: [
  ...
  MatSelectModule,
  MatOptionModule,
  ...
],

This ensures that you do not encounter any issues when trying to set the value of your mat-option.

Answer №4

I find it surprising that none of the user-provided answers are correct. How do I know? Because I have personally encountered the same issue myself.

The solution lies in importing import {MatSelectModule} from '@angular/material/select';

and including in the import statement MatSelectModule

Answer №5

To properly integrate the MatSelectModule, ensure you import it into AppModule.ts file.

import {MatButtonModule, MatCheckboxModule, MatSelectModule} from '@angular/material';

imports: [
    BrowserModule,
    AppRoutingModule,
    HttpClientModule,
    MatButtonModule,
    MatCheckboxModule,
    MatFormFieldModule,
    MatSelectModule
  ]

Answer №6

Most individuals tend to create a personalized component that they then include in the "shared.module.ts". When doing this, it is important to consider what needs to be imported into the personalized component itself

custom-select.module.ts

import { FormsModule } from '@angular/forms';
import { CommonModule } from '@angular/common';
import { NgModule } from '@angular/core';
import { MatInputModule } from '@angular/material/input';
import { CustomSelectComponent } from './custom-select.component';
import { MatSelectModule } from '@angular/material/select';

@NgModule({
  declarations: [CustomSelectComponent],
  imports: [CommonModule, MatSelectModule, FormsModule],
  exports: [CustomSelectComponent, MatInputModule],
})
export class CustomSelectModule {}

shared.module.ts

import { NgModule } from '@angular/core';
import { CustomSelectModule } from './components/customSelect/custom-select.module';
import { DatePipe } from './pipes/date.pipe';

@NgModule({
  declarations: [
    ...
  ]
  imports: [
    ...
    
    M̶a̶t̶S̶e̶l̶e̶c̶t̶M̶o̶d̶u̶l̶e̶,̶,
    CustomSelectModule,
    ...
  ],
  exports: [
    ...
    M̶a̶t̶S̶e̶l̶e̶c̶t̶M̶o̶d̶u̶l̶e̶,
    CustomSelectModule,
    ...
  ],
})
export class SharedModule {}
