Can you add controls dynamically, for example: when opening a window, only one sle control is used to load attachments, when you press "Add Attachment", a new sle control is added under the original sle control to display another attachment address

Use a data window to save each additional attachment path to the data window, and finally take it from the data window.

OpenUserObject is possible, but you can’t add code to the standard sle, unless you derive a class from sle
I still prefer to use dw, which is the strength of pb
