Handles selection operations for Events module.

This module provides functions for managing row selection state, including individual selection, select-all, and clear selection.

Customization

You can create a custom SelectionHandler:

defmodule MyApp.CustomSelectionHandler do
  use MishkaGervaz.Table.Web.Events.SelectionHandler

  # Custom toggle that limits selection to 10 items
  def toggle_select(state, id) do
    if MapSet.size(state.selected_ids) >= 10 and
       not MapSet.member?(state.selected_ids, id) do
      {:error, :max_selection_reached}
    else
      super(state, id)
    end
  end
end

Then configure it in your resource's DSL:

mishka_gervaz do
  table do
    events do
      selection MyApp.CustomSelectionHandler
    end
  end
end

See MishkaGervaz.Table.Web.Events, MishkaGervaz.Table.Web.State, and the sibling handlers SanitizationHandler, RecordHandler, BulkActionHandler, HookRunner, RelationFilterHandler.
