Topic: Different mdb-select labels depending on whether a value has been selected or not

1001albertpadilla free asked 4 years ago

How can I have different mdb-select labels depending on whether a value has been selected or not? For example, I want the label "* Department" if there's no selected value. But only "Department" if a value has been selected. mdb-select is set to start with a blank option.

How do you set the default value? Do you use reactive or template-driven forms?

        <mdb-select [(ngModel)]="employee.department.id" [options]="departments" name="departmentId" id="departmentId"
                    [optionHeight]="25" label="Department"></mdb-select>

departments -- is a regular array of Department object populated inside the ts file.

Do you mean this effect?:

HTML

TS

<pre class="prettyprint"><code> selected = '';
 dateOptionsSelect = [
 { value: '1', label: 'Today' },
 { value: '2', label: 'Yesterday' },
 { value: '3', label: 'Last 7 days' },
 { value: '4', label: 'Last 30 days' },
 { value: '5', label: 'Last week' },
 { value: '6', label: 'Last month' },
 ];

getSelectedValue(event: any) {
 this.selected = event;
 }
 getLabel() {
 if (this.selected === '') {
 return true;
 } else {
 return false;
 }
 }
</code></pre>

Hope it helps!
