Most databases / spreadsheets have some kind of field that you can pre fill a few options, which is called an enum field (or in non computing terms a static list).
An example of this type of field is Airtable’s status field or apple numbers “Pop-Up” field.
You simply write some options into the field when setting it up. Then when entering the data into the field only these specific options are available to enter.
A common example is… todo, in progress, on hold & done.
I think an enum field in Glide databases would be amazing. It would prevent having to setup a relation to a “utility” table (2 extra fields) and a lookup (a 3rd field) just to reference a predetermined list of (static) options.
