/**
 * Generic Dropdown Styles
 * Core dropdown and tooltip styles that can be used across all dropdowns
 * 
 * Usage:
 * - Add .dropdown-container to the wrapper element
 * - Add .dropdown-menu to the dropdown element
 * - Add .dropdown-tooltip (optional) for tooltip
 * - Add .dropdown-inner for the inner scrollable content area
 * 
 * Each specific dropdown should have its own CSS file for:
 * - Trigger button styles (unique to each dropdown)
 * - Option/item styles (unique to each dropdown's content)
