Control the level of flexibility for "Searchable list" validation (defined values or flexible input)

[anikbrazeau]

Description

At times the validation requirements are less flexible than the app currently allows for searchable list combobox component. This specification would be a nice feature enhancement depending on the use case.

Suggestion to give clients a choice in the "...More" options to be able to input additional free text or to be limited to the closed list / limited structured data / options presented? Some clients will have a list of "pre-defined values". Making the searchable list closer to a dropdown, acting more like autocomplete for known values.

Feedback from client

Just a thought, it may be a helpful feature in the future if the Searchable list has an option available (in the ..more settings) to have a closed list of choices, in which the input box is just a search to choose a pre-defined value. So basically, a dropdown that’s searchable. Or to allow a user to input a custom value as well as the ability to choose from the pre-defined list. This would behave more like an input box with autocomplete, for example an address input box that autocompletes if it has a known value but allows you to add an address that doesn’t exist. Although it may be confusing to end users unless this is communicated through a hint or instructions.

Expected behaviour

• Option to make list of options limited / strictly defined OR flexible / free to change
