regarding selecting multiple files from a folder using file open dialog box

[Am123]

I am making a project on D3 . The problem is on opening a file open dialog box , I want to select the folder . The folder contains 12 files. I want to select all the files and then pass it to D3 so that 12 pie charts will get displayed.

For Selecting Multiple file you should add 'multiple' attribute.
<input type="file" name="img" multiple>
