Use OpenBox to show additonal information on the product page

-- url of the page with the problem -- : www.2-rad-schwede.de
-- HikaShop version -- : 4.0.1
-- Joomla version -- : 3.9.2
-- PHP version -- : 7.0.16
-- Browser(s) name and version -- : mozilla latest version

Hi
To provide some additional information to the customer on the product page (e.g. for financing background information) I wanted to use your OpenBox functionality (from the checkout).
Due to the fact that we have, depending on the product type, different partners I created a new customer field (singe dropdown) and in the titles I tried to put the HTML code.
a href="index.php/service/rahmenhoehe-rechner?tmpl=component" rel="nofollow" onclick="return window.hikashop.openBox(this);" data-hk-popup="vex" data-vex="{x:450, y:480}">Rahmenhöhe-Beratung /a
The problem is that ONCLICK will not but stored in the title field so that a complete new page is loaded instead of show the OpenBox.
Any idea how to solve it? Is there an easier solution to do so?

Thanks in advance
Markus

Hi Nicolas,

thanks for the details and the background. I solved it by using the modal plugin.

That works great

best regards
Markus
