Pagination dropdown placement appears to be misplaced in the material design

Issue

I am currently facing a challenge while incorporating a <mat-table> with a <mat-paginator> in my project. The issue lies in the positioning of the items per page dropdown, which appears to be offset to the left and seemingly outside the Bootstrap container.

An image depicting this problem can be viewed here.


Code

The structure of my site is enclosed within a Bootstrap container as illustrated by my app.component.html:

<app-header></app-header>
<div class="container mt-3">
  <router-outlet></router-outlet>
</div>
<app-footer></app-footer>

The specific page causing the issue includes a basic material table with pagination at the bottom.

<div class="row">
  <div class="col-md-12">
    <mat-table *ngIf="items" [dataSource]="items" matSort>

      <!-- ID Column -->
      <ng-container matColumnDef="type">
        <mat-header-cell *matHeaderCellDef mat-sort-header> Type </mat-header-cell>
        <mat-cell *matCellDef="let row"> {{row.type}} </mat-cell>
      </ng-container>

      <!-- Provider Column -->
      <ng-container matColumnDef="provider">
        <mat-header-cell *matHeaderCellDef mat-sort-header> Provider </mat-header-cell>
        <mat-cell *matCellDef="let row"> <a href="https://eosauthority.com/account/{{row.provider}}" target="_blank">{{row.provider}}</a> </mat-cell>
      </ng-container>

      <!-- Name Column -->
      <ng-container matColumnDef="url">
        <mat-header-cell *matHeaderCellDef mat-sort-header> URL </mat-header-cell>
        <mat-cell *matCellDef="let row"> {{row.url}} </mat-cell>
      </ng-container>

      <!-- Country Column -->
      <ng-container matColumnDef="country">
        <mat-header-cell *matHeaderCellDef mat-sort-header> Country </mat-header-cell>
        <mat-cell *matCellDef="let row"> {{row.country}} - <span class="flag-icon flag-icon-{{row.country | lowercase}}"></span> </mat-cell>
      </ng-container>

      <!-- Updated Column -->
      <ng-container matColumnDef="updated_on">
        <mat-header-cell *matHeaderCellDef mat-sort-header> Updated </mat-header-cell>
        <mat-cell *matCellDef="let row"> {{row.updated_on}} </mat-cell>
      </ng-container>

      <mat-header-row *matHeaderRowDef="['type', 'provider', 'url', 'country', 'updated_on']"></mat-header-row>
      <mat-row *matRowDef="let row; columns: ['type', 'provider', 'url', 'country', 'updated_on']">
      </mat-row>
    </mat-table>

    <mat-paginator [pageSizeOptions]="[5, 10, 25, 100]"></mat-paginator>
  </div>
</div>

It appears that certain CSS files are required. You can add the following line to your style.css or style.scss:

@import "../node_modules/@angular/material/prebuilt-themes/indigo-pink.css";

After much troubleshooting, I have finally resolved the issue =D It turns out that some CSS code in Angular was conflicting with the pagination's original CSS code that works with the cdk-overlay-container. To fix this bug, I decided to extract the code from the file @angular/cdk/overlay-prebuilt.css and include it in my own CSS file. Additionally, I identified the necessary components and made the following adjustments:

//Include this in your CSS/SCSS File
::ng-deep {
  .cdk-overlay-container,
  .cdk-global-overlay-wrapper {
    pointer-events: none;
    top: 0;
    left: 0;
    height: 100%;
    width: 100%;
  }
  .cdk-overlay-container {
    position: fixed;
    z-index: 1000;
  }

  .cdk-overlay-pane {
    position: absolute;
    pointer-events: auto;
    box-sizing: border-box;
    z-index: 1000;
    display: flex;
    max-width: 100%;
    max-height: 100%;
  }
}

By implementing these changes, you can restore the original pagination design in Angular. If you desire a non-transparent dropdown selection, simply add the following lines to .cdk-overlay-pane:

background-color: white;
border: 1px solid rgba(128, 128, 128);

import { MatPaginatorModule } from '@angular/material/paginator';

If you haven't already, make sure to import the Material Pagination Module in your Angular project. Give it a try and let me know how it goes. Thank you!

Answer №4

When working on various projects, whether Bootstrap or Material themed, there is typically a designated theme folder containing important files such as theme-variable.scss and theme.scss for Bootstrap projects, or material-theme.css and material-theme.scss for Material projects.

The presence of the last two files is crucial for ensuring proper rendering of Angular-Material components. Even after importing the necessary modules for the component, these files are still required.

To incorporate these files into your project, you must import them in your styles.css file using the following line:

@import './theme/material-theme.css';

By following these steps, you can guarantee that tables or any other Angular-Material components will render correctly.
