I have a list that contains many items. I'd like to give my users the ability to select 10-20 items by "checking" them and then edit them all at once. Certain fields (item name, id, etc.) are item-specific and should not be edited, but other field values can be specified in bulk.
If I check one item, the "Edit Item" button is active, but as soon as I select 2 items, it is disabled. How can I add this feature to my application?
