Hello guys I´m having some problems getting my dropdown menu to collapse, in secondary pages that are saved in folders inside the folder of the master.page, I will leave an image so you can see how it is, The page that is not dropping down is in the “administração” folder, “Folder administração” he´s name is UnidadesOrganicas, the content page is empty, only with the master.page content, and the menu doesnt work, but if I use a secondary page in the Same folder as the master-page it works, I don’t know why, I will leave the master.page code in here.

(IM USING BOOTSTRAP 5)

Thank you for your help.
