Hello,
That JavaScript error is not coming from HikaShop. It is a known Joomla backend symptom that appears when another extension or the admin template loads its own version of Bootstrap, which then conflicts with the core collapse.min.js script that Joomla auto-loads on every backend page. When that conflict happens, every dropdown and modal that uses Bootstrap collapse stops working, including the "Select Menu Item Type" modal, which is why the dropdown stays greyed out regardless of which type you try to pick. The effect is not specific to our withdrawal type: you would hit the exact same issue trying to create a menu item for an article, a category list or anything else.
The causes are almost always one of the following, in this order:
- First, a stale Joomla cache or minified admin JS bundle. Go to System > Maintenance > Clear Cache, clear every cache group listed, then force-reload the menu creation page with Ctrl+F5.
- Second, a third-party administrator template. Log in to the backend, go to System > Templates > Administrator Templates, set Atum (the default Joomla admin template) as the default, then retry creating the menu item.
- Third, a backend plugin or module loading its own Bootstrap. Disable administrator-area plugins and modules one by one (start with any system / SEO / speed / cache / minify / custom form plugin) until the Select button works again.
- Fourth, an outdated Joomla patch level. Several backend modal JavaScript regressions have been fixed in recent Joomla 4.x and 5.x point releases, so make sure you are fully up to date.
I remember seeing this several times with frontend templates that would have a system plugin which would add their stuff on the backend and frontend instead of adding it only on the frontend.
