Fluxon.Components.Switch (Fluxon v1.2.0)

A versatile toggle switch component for binary choices and settings.

This component provides an accessible and customizable switch control that serves as an alternative to checkboxes, particularly suited for immediate actions and settings. While checkboxes are better for form submissions and multiple selections, switches excel at toggling states with immediate effect.

Usage

The switch component can be used standalone or within forms:

<.switch
  name="notifications"
  label="Enable Notifications"
  sublabel="Stay updated"
  description="Receive real-time updates about your account activity"
/>

Basic Switch

Form Integration

The component seamlessly integrates with Phoenix forms:

<.form :let={f} for={@form} phx-change="update_settings">
  <.switch
    field={f[:notifications_enabled]}
    label="Push Notifications"
    sublabel="Real-time updates"
  />
</.form>

Customization

The switch component offers various customization options through colors and sizes:

<!-- Different sizes -->
<.switch label="Small Switch" size="sm" />
<.switch label="Default Size" />
<.switch label="Large Switch" size="lg" />

<!-- Different colors -->
<.switch label="Success" color="green" />
<.switch label="Warning" color="amber" />
<.switch label="Danger" color="red" />

Switch vs Checkbox

While both switches and checkboxes handle boolean states, they serve different UX purposes:

Switches are best for immediate actions (e.g., toggling a setting that takes effect immediately)
Checkboxes are better for form submissions and multiple-choice selections
Switches suggest a direct state change, while checkboxes are more about selection/deselection
Use switches for binary settings (on/off, enabled/disabled) and checkboxes for agreement or multiple options
