tag_options {} - Hash of additional options to pass to the tag builder (e.g., data attributes, class, etc.)

Icon Support

The component supports two types of icons:

  1. App Icons: When left_icon or right_icon is one of the app icon names ("core", "manager", "submission", "hubs", "validation", "handling", "exits", "impact", "submission_extra"), the respective app icon will be rendered.

  2. FontAwesome Icons: When using MIcon compatible icons or FontAwesome classes (e.g., "fa-regular fa-info"), the icon will be rendered accordingly.

  3. Custom Icons: You can also pass custom icon classes that will be applied directly.

States

  • :enabled - Default state, button is interactive
  • :hover - Hover state (typically handled by CSS)
  • :active - Active/pressed state
  • :loading - Loading state
  • :focus - Focused state
  • :disabled - Disabled state, button is not interactive

Counter

When showCounter is true and count is provided and greater than zero, a counter badge is displayed. The counter_kind property controls the visual appearance of the counter.

Slots

left_icon

Renders an icon on the left side of the button:

<%= render LooposUi::FilterButton.new(text: "Filter") do |button| %>
  <% button.with_left_icon(icon: "info") %>
<% end %>

Slot attributes:

  • icon - Icon name or class (required)
  • Additional kwargs are passed to the icon component

right_icon

Renders an icon on the right side of the button:

<%= render LooposUi::FilterButton.new(text: "Filter") do |button| %>
  <% button.with_right_icon(icon: "chevron-down") %>
<% end %>

Slot attributes:

  • icon - Icon name or class (required)
  • Additional kwargs are passed to the icon component

JavaScript/Stimulus Controller

The FilterButton component includes a Stimulus controller (lui--filter-button) that provides dynamic functionality for button interactions.

Controller Behavior

The controller automatically handles:

  • Button state management
  • Integration with FilterBar component
  • Form submission handling when used within filter forms

Integration with FilterBar

When used within a FilterBar component, the FilterButton automatically:

  • Gets click handlers attached by the FilterBar controller
  • Manages selection state based on form inputs
  • Dispatches filter:toggle events when clicked
