+## Configuration
+
+```json5
+{
+    closeOnClick: true, // boolean; will menu.close(), after item is selected. [default: true && menu.onClickFallback();]
+    closeOnClickOutside: true, // true or function(); it will menu.close(), when item is not selected and click is outside of menu. [default: true]
+
+    ui: { // ui customization
+        fontSize: "38%", // text font-size of elements inside {menuContainer}, eg: text in {itemSector} [38%]
+        classes: {
+            menuContainer: "menuHolder", // whole radial-menu container, created dynamically! see: {params.parent}
+            menuCreate: "menu",
+            menuCreateParent: "inner", // main menu [{menuCreate} inner]
+            menuCreateNested: "outer", // nested menu [{menuCreate} outer]
+            menuOpen: "open", // menu is visible [open]
+            menuClose: "close", // menu is not-visible [close]
+            itemSectorActive: "sector", // item, which is active and can be selected [sector]
+            itemSectorNested: "more", // item, which has nested items... [more]
+            itemSectorDisabled: "dummy", // item, which is not-active/disabled [dummy]
+            itemSelected: "selected", // item, which is selected [selected]
+            closeBackButton: "center", // centered {close} or {back} button [centered]
+            iconsContainer: "icons", // item's icon container [icons]
+        },
+        item: { // pre-defined items: {close} and {back} in similar way like: {menuItems}
+            close: {title: "Close", icon: "#close"},
+            back: {title: "Back", icon: "#return"},
+            // FYI:
+            // 1) if u want to change, eg: 'close' icon, just use item.close.icon = '#myIconId'
+            // 2) if u want to override default 'icon' generation, see: RadialMenu.defaultValues.ui.item.{close, back}.symbol
+            // 3) to change item's colors, etc use: CSS:
+            //      svg.{menuCreate} > g.{itemSectorActive} > text,
+            //      svg.{menuCreate} > g.{itemSectorActive} > use {...}
+        },
+        nested: { // nested ~ inner-menu behavior
+            icon: "#return", // string(iconId:'#return') or true(for parentItem.icon)
+            title: true // show nested title?
+        },
+        moveByWheel: true, // navigation by mouse-wheel. [default: true]
+        moveByKeys: { // navigation by keys. [default: true]
+            enabled: true,
+            back: ["escape", "backspace"],
+            select: ["enter"],
