How do we set the fontSet attribute on MatIcon in order to get the Material Symbols to render.

I'm trying to render the expand_content symbol however it is not rendering as shown in the material icons font.

This is the markup for rendering it as a span element:

<span class="material-symbols-outlined">
expand_content
</span>

This is how Angular Renders it: .ts,src%2Findex.html

This is the markup:

<mat-icon fontSet="material-icons-outlined">expand_content</mat-icon>

And this is the icon I'm trying to render.

• javascript
• angular
• typescript
• angular-material
• material-icons

• hmm i can see the icon rendered in the stackblitz – cmgchess Commented Feb 25, 2024 at 20:16
• @Yogi Yes indeed I'm looking for it to render the expand icon in the link you shared. – Ole Commented Feb 26, 2024 at 0:32
• Indeed. The fontSet attribute is usually used to control which icon is rendered and how, so I'm sure if it has the correct value, the icon will render. – Ole Commented Feb 26, 2024 at 14:30

The class material-symbols-outlined to mat-icon like this.

 <mat-icon class="material-symbols-outlined">expand_content</mat-icon>

There's notes on this in this issue.

Also there's an NPM package with more detailed instructions for Material Symbols use in general.

Someone else (brilliant) shared this:

 provideAppInitializer(() => {
      const initializerFn = ((iconRegistry: MatIconRegistry) => () => {
        const defaultFontSetClasses = iconRegistry.getDefaultFontSetClass();
        const outlinedFontSetClasses = defaultFontSetClasses
          .filter((fontSetClass) => fontSetClass !== 'material-icons')
          .concat(['material-symbols-outlined']);
        iconRegistry.setDefaultFontSetClass(...outlinedFontSetClasses);
      })(inject(MatIconRegistry));
      return initializerFn();
    })

add this to your appConfig providers so all mat-icons will use the fontset you register in here.
