Hi there I've added a select box into my angular application. When loading the page, the placeholders are shown correctly. But when I want to reset the Search-Criterias by setting the selected value to "0", the placeholders are no longer displayed.  (0 is a non-existing value in the select-options) How can i reset the selectbox so that the placeholder is displayed again?
<mdb-select[options]="eventDropDown"placeholder="Events"[(ngModel)]="searchEventId"name="eventId"></mdb-select>

If you use an older version of the component (mdb-select):

  1. Use template reference variable #select on the <mdb-select> element:

  2. Use ViewChild to get access to the select element in the Typescript file:

    @ViewChild('select') select: SelectComponent

  3. Use select clear() method to clear the selections:

    clearSelection() { this.select.clear(); }

This public method is currently not available in the new version (mdb-select-2), but this problem should be fixed in the near future.

How to clear selected option from TypeScript file?

Dear MikeH, You can use [allowClear]="true" input to add reset button that will appear on the right side of the select input when you choose an option. Regards, Arek
