Mild (sweet?) onions flopped - how to extend life

I have 100 mild onions that aren't a storage variety that have flopped.  I figure they'll be good for a couple weeks and then I need to dehydrate or freeze them for later use.  To get the most fresh storage life from them, should I pull them and put them somewhere dry or leave them in the garden?  

Mike,  when my onions tip over I pull them.  I don’t have good success leaving onions in the ground when they are done….meaning when the tops tip over. For me they tend to go bad.

I’d pull them and use them or as you said dry or freeze if they are not storage onions.

Treat them like storage onions, pull and dry they won't last 8 months, but they will last at least a month which will give you some time to deal with them.

I agree with the above, pull them.

Thanks everyone!  This is my first time planting non-storage onions so it's a learning process
