How can I drag and drop field names from Data Sources for a mail merge form letter?

I’m wanting to do mail merge. So In the ODT Document I hit F4 to view the Data Sources.
I then go to the correct sheet in my database. When I then try to drag the header of the column from the data source to the actual document nothing happens (the header should actually be displayed in brackets, so that the word can be replaced with the words in the column for mail merge…).

Any help/workaround would be greatly appreciated.

I’m using version:
Build ID: 0a0440ccc0227ad9829de5f46be37cfb6edcf72 on Mac OSX 10.9.1

I’m having the same problem. I can select individual data elements that turn into a small green circle with a ‘+’ in the middle and drag them to the document but when I try to drag a field heading it gives me a small black square that immediately jumps back to the data source.

Any suggestions?

I think I answered my own question. Try this. Instead of selecting the field header (as described in the documentation LibreOffice 4.0 Writer Guide Page 310), select and drag any row of data to the document, I just used the first row. You will see a dialogue asking if you want to insert as ‘Table’ ‘Fields’ of ‘Text’, select ‘Fields’ and choose the field/s you want to insert. Once you get them into the right order and format, click ‘ok’. The selected fields carry forward through each occurrence of the data for each merged document. It seems to be working.
