I am using max mega menu wordpress plugin for implementing menu. Desktop view is working fine but in mobile view it is not expanding on clicking arrow. I tried multiple option and script to work but not found any thing relevant to it.
You can check below link-
With the free version of this plugin, under Mega Menu -> Mega Locations, select the menu you want to edit, click Advanced, and try out the options under Click Event Behavior. https://www.megamenu.com/documentation/mobile-menu/#click-event-on-mobile
