Try to use widget “file picker”, i can upload one file, but i can`t upload many files at one, in database type of this column is : “varchar(max)”.
Welcome to the ForestAdmin community !
The filepicker is designed to accept only one file for string fields. The multiple file picker is available only available for arrays type fields.
As is if you need to store multiple files into one string field, ForestAdmin would not know how to store those files properly.
