no dropdown menue

Sound like you have issue with JavaScript.

Can we have more information about

• Versions you use
• Your browser
• You browser console output and if you see any errors

One common issue might be loading bootstrap twice: once from theme and once from somewhere else: library or module.

Hi,
thanks for gettin´ back to me here.

• so I using the version Bootstrap4 3.0.1
• the misbehaviour occurs in all roles incl. guests
• the problem is not ependent on the browsers I use: firefox 110.0 (64bt) or chrome 110.0.5481.100 864bit)
• the problem is online and on my local docker install
• on all other sites I made, the bootstrap subtheme does not make these problems after having updated the base theme on 3.0.1

thx

Hi,
well I could solve one problem.
When I click on parent the submenue opens. I gave parent as link one of the child links.
As this was not like this before, dropdown did not work at all.

parent
---child1
---child2
---child3

Well, now after click on parent the complete submenue stays open.
Even if I I move the mouse cursor away.

2 Problems were present here:

1) The bootstrap theme only adds the data-toggle="dropdown" to the menu ID main due to the fact, that this only happens in themes/contrib/bootstrap4/templates/navigation/menu--main.htm.twig. But we had another menu ID so I copied that file to our child theme and renamed to file to match the correct menu ID

2) The Menu block positioned in the block layout needed to have the option Expand all menu items enabled.

Nothing to do with JS.

Thanks @kevin.pfeifer
