+ * ## Custom Plugin Positioning ({@link MapConfiguration.layout | Standard Layout})
+ *
+ * When `layout` is set to `'standard'`, a custom plugin can be rendered in one of two ways:
+ *
+ * 1. **As part of the IconMenu**: Set {@link PluginOptions.renderType | renderType}
+ * 		to `'iconMenu'` and configure the plugin in the IconMenu's
+ * 		{@link IconMenuPluginOptions.menus | `menus`} configuration.
+ * 		The IconMenu will handle positioning and rendering the plugin at the designated location.
+ *
+ * 2. **Independent with CSS positioning**: Set {@link PluginOptions.renderType | renderType}
+ * 		to `'independent'` (default). The plugin is responsible for its own positioning
+ * 		using CSS (e.g., `position: absolute`) within the map container.
