required fields should not be clearable?

[MaZZly]

<sh-select name="tz" [options]="timeZones" [(ngModel)]="project.tz" required>
</sh-select> 

Should not show an option for clearing the input IMO, as the field is set to required

Use the showClear property:
[showClear]="false"

Perfect, thanks! couldn't find that in any documentation.

Maybe add the available attrs in a table to the readme?
