A flexible, draggable link picker for constructing site navigation menus, big or small, in Umbraco 8.
All credit for the initial plugin goes to Callum Whyte.
After installing the package, you will have a new property editor called MegaNav in the Umbraco backoffice.
Here you can configure the "Max depth" of the navigation - the maximum number of levels deep at which an editor can place nav items. You also have the option to prevent nav items where the umbracoNaviHide property has been set from rendering on the front-end - these items will still appear in the backoffice but not on your website, you can still edit or change them as you wish. By default both of these settings are left unset.
Now in V8 you can set the querystring / anchor in a seperate input box the same way as the MultiUrlPicker.
Now your Data Type is ready, we need to add it to a Document Type. This is done in the usual way - you will find Meganav appears in the "pickers" section when selecting a property to add.
