Hi friends, I'd like to create a dropdown text as below in the XML Editor of Experience Manager. What elements should I use? What steps should I do? Tks!

I can't find a place to change my topic Name or template (concept, reference, glossary...) after the file is created. If I want to change, is deleting and re-creating a new file the only way? Do I have other options?

Hi everyone! I uploaded files to AEM Assets, but I see process failed. However, I can still open, view, and edit the content. Please help me with this.TKS
