How to Change the Tooltip Position in Angular Material Paginator

The Angular Material Paginator component is a powerful tool for navigating through large datasets. It offers a user-friendly interface with helpful tooltips that provide context for each page number. However, sometimes the default tooltip position may not be ideal for your layout. Fortunately, Angular Material allows you to customize the tooltip position easily.

Scenario: Understanding the Problem

Let's say you have a paginator within a tight layout. The default tooltip position, which is below the page number, overlaps with other elements. This creates a frustrating user experience as the tooltip content becomes obscured.

Original Code (Default Tooltip Position):

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

Customizing the Tooltip Position: Using matTooltipPosition

Angular Material provides the matTooltipPosition directive to control the tooltip's position. You can use it to place the tooltip above, below, before, or after the page number.

Modified Code (Tooltip Position above the page number):

<mat-paginator [length]="100" [pageSize]="10" [pageSizeOptions]="[5, 10, 25]" 
  matTooltipPosition="above">
</mat-paginator>

Explanation:

  • The matTooltipPosition directive is added to the mat-paginator element.
  • We set the directive's value to above to move the tooltip above the page number.

Available matTooltipPosition Values:

  • above: Places the tooltip above the element.
  • below: Places the tooltip below the element (default).
  • before: Places the tooltip before the element (left of the element).
  • after: Places the tooltip after the element (right of the element).

Further Customization: Overriding Default Styles

For more advanced tooltip customization, you can override the default styles using CSS. This gives you greater control over aspects like background color, font, and arrow styling.

CSS to Customize Tooltip Style:

.mat-tooltip-panel {
  background-color: #f0f0f0; /* Customize background color */
  font-size: 14px; /* Customize font size */
}

.mat-tooltip-arrow {
  background-color: #f0f0f0; /* Customize arrow color */
}

Adding the CSS to your project:

You can add this CSS to a separate stylesheet and then include it in your Angular application using the <link> tag in your index.html file.

Conclusion: Achieving a Seamless User Experience

By customizing the tooltip position and style, you can ensure a smooth and intuitive user experience within your Angular Material paginator. This simple adjustment can significantly enhance the usability of your application, preventing frustration and providing users with a more enjoyable experience.

Remember: Always test your customizations thoroughly to ensure they align with your overall design and user requirements.
