Is it feasible to customize Angular Material Constants within select.ts?

I am looking for a way to dynamically set the height of a select element by passing a variable, but the height is currently a constant in the material code (select.ts).

Check out the mat-select documentation

View the source code on Github: material2 / select.ts

Is there any way to override this constant using providers or any other method?

I have come across solutions involving custom css styling:

1. Utilizing ::ng-deep

2. Using ViewEncapsulation

3. Setting class styles in style.css and using !important

4. Implementing panelClass

However, since these solutions involve css, could they potentially lead to css pollution?

::ng-deep .mat-option{
   height: 2.5em; 
} 

mat-option{
   height: 2.5em !important;
}

In conclusion, if I cannot override the constant in select.ts, should I be concerned about potential issues arising from using CSS in the future, or would it be acceptable in my situation?

Answer №1

After much experimentation, I have decided to implement the following code for custom material theming instead of using the component's css.

mat-option{
   height: 2.5em !important;
}

Check out this guide on custom material theming

It turns out that according to both 'Official Docs' and a reply in an 'Official GitHub issue', this method 'has never been supported.'
