Properties

openOnMount (boolean)

This option allows you to initialize the push menu as open on load.

nodes (Object)

This property accepts an object with the definition for the menu. see the example for a sample menu definition

propMap (Object)

APIs can define/give a different structure or property names for required fields. This give the user the option to tell react-push-menu which property on the node/menu item to find the value it's looking for.

Mapping	Description
id	the id property of the node
displayName	This is the text that will appear in the menu option.
linkClasses	These are class names that will be added to the menu option.
expanderClasses	These are class names that will be added to the menu option's expander given it has defined children.
url	This tells the library which prop the url for the menu item is located. will default to a hash (#) if none is found
childPropName	This is the property name that holds the children of each menu item node. We realize that data driven menu may differ and it is important to customize the properties that may hold the required data. default: children

eg.

<PushMenu
  propMap={{
    displayName: 'title',
    id: 'id',
    linkClasses: 'classes',
    expanderClasses: 'expClasses',
    childPropName: 'children',
    url: 'url',
  }}
></PushMenu>

onNodeClick (function)

This is an onClick callback fired when you click the link of a menu item. Please note it won't be fired when you click the expand component for a menu item.

eg.

<PushMenu
  onNodeClick={(e, context) => {
    /**
      {
        // state
        node: Record<string, any>; // the current node
        nodes: Record<string, any>; // full menu tree
        propMap: PropMap;
        visibleMenus: Array;

        // actions
        addMenu: (node) => {};
        removeLastMenu: Function;
        closeMenu: Function;
        openMenu: Function;
        openSubMenu: (node) => {};
        toggleMenu: Function;
      }
     **/
    console.log(context);

    // following line will close the menu completely
    context.closeMenu();
  }}
></PushMenu>

onMenuExpand (function)

This function triggered when a sub menu is expanded.

<PushMenu
  onMenuExpand={(e, context) => {
    // do something
    // return false to prevent default behaviour
  }}
></PushMenu>

linkComponent (React.Component)

You can fully customize the link of the menu by passing in a React Component to this property. It will be instantiated with the data object which contains the current node being interacted with. (props.data). To see an example please see LinkComponent.js

backComponent (React.Component)

You can fully customize the back link of the sub menus by passing in a React Component to this property. It will be instantiated with the data object which contains the current node being interacted with. (props.data).

backIcon (ReactNode)

If you don't specify a backComponent, you can at least need specify an icon to use for the back component

<FaChevronLeft />

expanderComponent (React.Component) (Required)

You can fully customize the expander link of the sub menus by passing in a React Component to this property. The expander is the chevron-right that appears when a menu item has children. It will be instantiated with the data object which contains the current node being interacted with. (props.data).
