Check the properties for that container in the Design tab, and notice the ID: dropdown-1.
Go back to the Inspector tab and select the text above the dropdown container with the classes button dropdown-btn.
Back to Design with the text selected, and open the attribute Data-toggle and see the value: dropdown-1.
Now, if you check the other dropdown panels and their belonging text, you will find that you have used the ID dropdown-1 several times. All the IDs have to be different, and the data-toggle value has to point to the corresponding ID.
Ha en riktig god dag!
