Having trouble adjusting the appearance of the dropdown menu in Angular Material's Select component

I've been attempting to adjust the style of the overlay panel within an Angular Material's MdSelect component in order to change the default max-width property of 280px.

I have tried various methods, such as using '!important' to override the mat-select-panel class or passing a custom class through the panelClass input (the class I passed does appear in the attribute, but it doesn't seem to be applied).

Has anyone encountered this issue before? Any suggestions on how to resolve this?

Thank you!

Answer №1

To customize the styling of a child component from a parent component, you can utilize the /deep/ instruction in the CSS.

Check out more details here.

If the specific component you want to modify has the following structure:

<div class="bar">...</div>

You can override its styles by adding the following code to your parent or application-level CSS:

/deep/ .bar {
   [ ... ]
}

Answer №2

One possible solution is to define it in the main CSS file.

.cdk-overlay-pane {
  .mat-select-panel {
    max-width: 700px;
  }

}
