I want my users to upload a document.
I know we can use doc library to upload docs. But Is there any way of providing a field to upload a file in SharePoint survey or custom list?
If the name of your list does not appear, click View All Site Content, and then click the name of your list.
Point to the item, click the arrow that appears, and then click Edit Item.
Click Attach File.
NOTE If you do not see the Attach File option, your list may not support attachments.
In the Name box, enter the path to the file you want to attach, or click Browse to locate the file.
Click OK.
TIP After the item is attached, it will appear in the Attachment section of the list item.
There is attachment option in sharepoint list. Here you can attach a document with the list item. May be you can use that.
