The menu is built exactly the same way on every platform. Only the way Navi+ connects to your website is different.
1Wix
Install Navi+ from the Wix App Market, then open the app in the Wix Dashboard. Navi+ attaches itself to your website, so you don't need to paste any code.
2WordPress
Install the Naviplus Menu Builder plugin, open Appearance > Naviplus Menu Builder, and turn on Embed Navi+ Menu Builder into website on the Connection tab.
3Other websites
Webflow, Squarespace or a site you code yourself: copy your code snippet (it already includes your account code) and paste it once into the head tag.
The code looks like this (NAVI123456 is an example; yours will be different):
<script>(window._navi_setting ||= []).push({
token: "NAVI123456"
});</script>
<script src="https://live.naviplus.app/start.js" async></script>
If you already use the WordPress plugin, don’t also paste this code, so Navi+ doesn’t load twice.
Menus that need a spot on the page (Desktop Mega Menu, Icon Menu…): see Where each menu type is placed. Features that pull data directly from Shopify (products, collections, Markets…) are only available on Shopify.
Other platforms
The steps above are for Shopify — the default way.
On Wix, Navi+ attaches itself to your website when you install it, so you don’t need to paste any code.
For WordPress and other websites, see sections 2 and 3 above.
