I would like your help to identify the reason for the select option does not appear in angular 6 mat-paginator. And how to set style for Back button and Next Button.
I'm trying follow the example below:
https://stackblitz.com/angular/anvplbamrbj?file=app%2Ftable-pagination-example.html
In example above when I click on mat-option from mat-paginator the select option appear over the table. When I copy this example for my project the select option from mat-paginator appear below the table. I don't know why does it happen.
As we can see in print sreen, the mat-paginator is working, but when I click on "itens per page" options" The select option appear invisible (I only can see the select option when I inspect element from web page.
So I think that this problem is in some CSS file, but I don't know how to fix it?
follow my code below:
list-devices.component.html: I only copy and past the example from stackblitz.com
<div class="mat-elevation-z8">
<table mat-table [dataSource]="dataSource">
<!-- Position Column -->
<ng-container matColumnDef="position">
<th mat-header-cell *matHeaderCellDef> No. </th>
<td mat-cell *matCellDef="let element"> {{element.position}} </td>
</ng-container>
<!-- Name Column -->
<ng-container matColumnDef="name">
<th mat-header-cell *matHeaderCellDef> Name </th>
<td mat-cell *matCellDef="let element"> {{element.name}} </td>
</ng-container>
<!-- Weight Column -->
<ng-container matColumnDef="weight">
<th mat-header-cell *matHeaderCellDef> Weight </th>
<td mat-cell *matCellDef="let element"> {{element.weight}} </td>
</ng-container>
<!-- Symbol Column -->
<ng-container matColumnDef="symbol">
<th mat-header-cell *matHeaderCellDef> Symbol </th>
<td mat-cell *matCellDef="let element"> {{element.symbol}} </td>
</ng-container>
<tr mat-header-row *matHeaderRowDef="displayedColumns"></tr>
<tr mat-row *matRowDef="let row; columns: displayedColumns;"></tr>
</table>
<mat-paginator [pageSizeOptions]="[5, 10, 20]" showFirstLastButtons></mat-paginator>
