Input Stepper: Overview

A web component that enables the user to increase and decrease a numeric value by predefined range. It is a combination of two buttons and a number input field with an optional slot after to suffix the extra information.

  <lion-input-stepper max="5" min="0" name="count">
    <label slot="label">RSVP</label>
    <div slot="help-text">Max. 5 guests</div>
