How to export selected entries in 1Password 8?

OK, playing around in the interface, here is a work-around that I just used to get "selected" passwords out of my vault and store them elsewhere. YES, you do have to export the entirety of your 1Password account of usernames/passwords, but you will not be keeping all of them, and I do encourage your to delete the remainder of the unencrypted data as mlaferle mentioned.. unencrypted data-at-rest increases the risk exposure.

BEFORE EXPORTING:
1. Create/rename a tag that can be used to "mark" the entries you want to "selectively export" (I say this, b/c you are exporting everything, but the tagging will let you locate the specific items quickly, and you can purged the unwanted items just as quickly).
2. Search or select the items you want to "export", and use the feature of dragging those entries on top of the tag shown in the left-side-panel. This will apply that tag to all those items.

3. EXPORT all items in CSV format. (enter your password, etc..)
4. Open the file, and there will be a column called "tags". Find/Sort those column to find those entries with the specific tag (using Excel, or text editor or choice).

5. Extract those items to wherever you want. I highly encourage you to encrypt that content to keep it safe (so many options available for a variety of OSs).
6. DELETE the remaining data (reduce exposure).

There ya go! NOW.. this NOT a substitute 1Password/Agile team! Please re-enable the export of vault or selected items features.
