I’d like to add a selection (choice) metadata field to a workspace. According to the docs, the format of the additional\_info field should be like: > Selection: A select box with a set of value that you can define using the “Additional Info” field, using the following syntax: key1|Label 1,key2|Label 2,key3|Label 3 However, this does not work for me. The selection dropdown is always empty, regardless of how I format this field. ---

Hi, are you talking about this feature ? [image](https://prnt.sc/if418o) ---

Yes. How should I format the selection options in additional\_info field? Either the docs are incorrect, or there’s a bug with displaying the selection options. I added the Selection metadata field, and added selection options to the additional\_info field (following the docs), but the selection drop-down on the main page is empty. ---

Hi, yes it should be `key|label`. I will ask the devs about it. Could you look at [this picture](https://prnt.sc/ih85fa) and tell me if your settings looks like those. ---

> [@r0bbyt](#): > > key1|Label 1,key2|Label 2,key3|Label 3 Thank you for confirming, this helped me find the bug. When I create a meta data field id with an underscore, this feature breaks. e.g., this does not work: ![39](https://canada1.discourse-cdn.com/flex032/uploads/pydio/original/1X/f53d4998114972d92fb805c2d3b5a7797cf727e2.png) ---

Also, using an underscore in the field ID breaks the ability to search. It seems the “\_” is being incorrectly translated to “-” when written into the .ajxp\_meta file. ---

Here are my steps to reproduce this bug: Create a new file system based workspace, add Text Metadata feature, add a new field (selection type), set the field ID to be “does\_not\_work”, set Additional Info to “key1|Label 1,key2|Label 2,key3|Label 3”. Then navigate to the workspace, upload a file, edit the metadata, and the selection dropdown will be empty.
