The mat-select
readonly attribute is used to make a Material Select component non-editable or unselectable by the user. When the readonly attribute is applied, the user cannot open the dropdown list, select an item, or interact with the select control in any way. This can be useful when you want to display the selected value without allowing the user to change it.
Example:
Here’s an example of how to use the readonly
attribute in a mat-select
component:
<mat-form-field>
<mat-label>Favorite Fruit</mat-label>
<mat-select readonly [value]="favoriteFruit">
<mat-option value="apple">Apple</mat-option>
<mat-option value="banana">Banana</mat-option>
<mat-option value="orange">Orange</mat-option>
</mat-select>
</mat-form-field>
In the above example, the readonly
attribute is added to the mat-select
element. The [value]
attribute is used to bind the selected value to a variable named favoriteFruit
. Therefore, the mat-select
element will display the value of the favoriteFruit
variable, but the user will not be able to make any changes.
