Selectable box in a web for for uploading

Hello All,

I have a web form for uploading. When a user selects “Attach” file, the file appears under it. You can add multiple files to this form before submitting the files. Here is the formula:

@If(@AttachmentNames=“”;“-- there are no files to upload --”;@Implode(@AttachmentNames; @NewLine))

I am looking for a way to add a “box” next to the files so one can disselect them and with an action button, delete the “checked” files.

Does anyone have any ideas?

Thank you in Advance :o)…
