推荐答案
将CSS添加到select块和mat-form-field块中,它们可以自动应用于所有select元素:
Add CSS to both select block and mat-form-field block, these can be applied automatically to all the select elements:
<mat-form-field class="readonly-wrapper">
<mat-select class="readonly-block" placeholder="Choose an option" [disabled]="disableSelect.value">
<mat-option value="option1">Option 1</mat-option>
<mat-option value="option2" disabled>Option 2 (disabled)</mat-option>
<mat-option value="option3">Option 3</mat-option>
</mat-select>
</mat-form-field>
CSS代码:
.readonly-wrapper {
cursor: not-allowed;
}
.readonly-wrapper .readonly-block {
pointer-events: none;
}
