Hey. Thank you for the suggestion. 👍 The tag was only quite recently introduces, that's why the number of uses is still quite low. I would however say that it would be good to have a field for this tag in the editors already now.

This pull request is however still missing the json file for the field of the new tag: You would have to create a new file in data/fields/toilets/menstrual_products.json and fill in the required details (e.g. a label for the field, the possible options, etc.). You might use the field for the wheelchair tag as a template. You could use something like Free Menstrual Products as a label. I'm currently not quite sure how to properly describe the option for the limited tag value… Maybe something like Limited to Some Stalls could work?!

An alternative would be to add this tag as a checkbox field ("type:" "check") for now and monitor how the tag is going to be used in practice over time.

Thank you so much for the feedback, I added the required file. I liked the Limited to Some Stalls option and used that and kept the radio type.

I tried the changes in the preview and toilet:menstrual_products is correctly suggested. On the other hand the values are not whereas toilet:wheelchair works as expected. So there is no dropdown menu to select a value. Is that expected or did I do something wrong?

You might have misunderstood how the prerequisiteTag is interacting with a field: here it had prevented the field from being included in the list of suggested additional fields. I've changed that in d18c7cc, and AFAICS it should work properly now.
