Unable to utilize material tabs in this situation

Discovering the material tabs feature at https://material.angular.io/components/tabs/api#MatTab got me excited to implement it in my project.

After adding the suggested import, I encountered an issue where I couldn't find the module "@angular/material". Fortunately, I found a solution on Stack Overflow and successfully imported the necessary components into my maintab component.

However, even after resolving the import error, the mat-tab links were still not functioning properly. Below is the code for my maintab.component.ts:

import { Component, OnInit } from '@angular/core';
import {MatTabsModule} from '@angular/material';

@Component({
  selector: 'app-maintab',
  templateUrl: './maintab.component.html',
  styleUrls: ['./maintab.component.css']
})
export class MaintabComponent implements OnInit {

  constructor() { }

  ngOnInit() {
  }

}

And here's the code snippet from my maintab.component.html:

<mat-tab-group>
  <mat-tab label="One">
    <h1>Some tab content</h1>
    <p>...</p>
  </mat-tab>
  <mat-tab label="Two">
    <h1>Some more tab content</h1>
    <p>...</p>
  </mat-tab>
</mat-tab-group>

Despite this implementation, I continued to encounter errors such as:

Error: Template parse errors:
'mat-tab' is not a known element:
1. If 'mat-tab' is an Angular component, then verify that it is part of this module.
2. If 'mat-tab' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message. ("<mat-tab-group>
  [ERROR ->]<mat-tab label="One">
    <h1>Some tab content</h1>
    <p>...</p>
"): ng:///AppModule/MaintabComponent.html@1:2
'mat-tab' is not a known element:
1. If 'mat-tab' is an Angular component, then verify that it is part of this module.
2. If 'mat-tab' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message. ("
    <p>...</p>
  </mat-tab>

I am currently unsure about what steps to take next to resolve these issues.

Answer №1

The issue arises when a module is imported into a component. To resolve this, the MatTabsModule must be imported into the AppModule and included as a provider. If the MaintabComponent is declared in the App module, this solution will work effectively.

If the MaintabComponent is not declared in the AppModule, then the MatTabsModule should be imported and provided in the module where it is declared instead of the AppModule.

(If you continue to encounter difficulties, kindly provide the code for the module where this component is declared for further assistance)

Answer №2

Dealing with a similar problem, I also encountered errors due to MatTabModule being in the node_modules folder.
The resolution for this is simple: Open your command prompt and execute

npm install --save @angular/cdk @angular/material

Answer №3

In my case, I included MatTabsModule in the exports array instead of the imports section, and that solved the issue for me.
