Remove - add Files to List

Remove the functionality to add files to the list? Please help me

Please, try to use the setFilesLimit() method:
docs.dhtmlx.com/api__dhtmlxvaul … limit.html

I apologize. In case of the dhtmlxForm upload item such feature is not supported.
You may only try to use the “file” item:
docs.dhtmlx.com/form__controls_list.html#file

can we remove the add files to the list icon?

Unfortunately it is not available.
