[Feature] Improve Encounter Form Error Validation

Feature Request

• Requested By: Brendan
• Associated Components: Frontend

What Domain Problem Is Being Solved

• why are we making this feature request and how are we hoping to fix it?

When the encounter form submits and there are multiple errors it only shows the topmost error in the form. We want to have all errors show simultaneously and with help text.

Technical Scope

• Showing only a single error on submission is the browser performing the validation. Need to disable or override.
• Use a library to handle form validation and errors. react-hook-form is a good candidate.
