Create the TaskFilter Template

Now we can turn our attention to the taskfilter.component.html template. We’ll start by displaying an error alert before going into the filter specific UI elements:

<div class="taskFilterWrapper">

<div class="alert alert-danger warningAlert taskFilterAlert"

*ngIf="filterError">

<h2>{{filterError}}</h2>

</div>

</div>

The whole template is placed in a div with the CSS class taskFilterWrapper. Add this to the taskfilter.component.css file:

.taskFilterWrapper {

display: flex;

height: 100%;

flex-direction: column;

}

This sets up the whole task filter for Flexbox sizing, then the div that creates the alert. It has a custom class after the regular classes:

.taskFilterAlert {

padding: .2rem 1.25rem;

}

This just minimizes the padding so the TaskFilter alert doesn’t take up too much space. Then, the div uses a *ngIf to hide the alert if the filterError value is empty. Create the filterError value in the taskfilter.component.ts file:

filterError : string;

Finally, the alert code displays the alert text, if relevant, and that starts our task filter template.
