Hi Nibelungen,
I am sorry to inform that our technical support services are dedicated for bug fixing, products maintainence or general advice on how to use the products only. All custom works that requires to extend products’ core features as shown on our demo site are not subject to support coverage and should be handled by clients.
Thus, I am sorry that we could not handle your below customization request as it would delay the time for supporting other clients and developing new products for monthly release commitment.
<blockquote>I would like to customize my megamenu so that if the user clicks on the dropdown arrows, a dropdown list will be displayed (and its menu link will be styled also as in the regular megamenu), and if the user just clicks on the menu links it will take them to that link (ie category list view, etc). And hovering will not trigger dropdown lists.
So is that possible with a simple modification? </blockquote>
Thank you for your understanding and I highly recommend you to post the projects on Joomlancers.com in case you need an expert to take up custom work as this is a good freelance portal.
