FYI, it looks like you might need the following changes to make JUX Mega Menu compatible with Joomla 4.3.1. There might be others too, but these were the ones that we needed.

file: modules/mod_jux_megamenu/helper.php

-replace all "->params" with "->getParams()"

-replace "JSite::getRouter()" with "JFactory::getApplication()->getRouter()"

-replace "&JSite::getMenu()" with "JFactory::getApplication()->getMenu()"

-replace "$router->getMode() == JROUTER_MODE_SEF" with "JFactory::getApplication()->get('sef', 0) == 0"

Never mind. I see the jux mega menu download has 2 packages inside. One for Joomla 3 and one for Joomla 4. We just needed to reinstall this extension after upgrading to Joomla 4 with the Joomla 4 package.

It is compatible. You have to unzip1st_jux_megamenu_3.3.6.zip and there is pkg_jux_megamenu.Joomla4.zip. Install it.
