Select

Om komponenten

Select viser brukeren en nedtrekksliste der ett alternativ kan velges.

Egnet til:

  • Skjemaer hvor bruker skal velge ett alternativ fra en liste
  • Når siden for det meste er skjemabasert.

Uegnet til:

  • Når bruker har få alternativer å velge mellom. Bruk da heller RadioGroup
  • Når bruker kan velge flere alternativer i listen. Da bruker du heller CheckBox

Husk på

  • Alle tekstfelt bør ha et tilknyttet label eller instruksjon som viser hvordan skjemaet skal fylles ut.
  • Label (ledeteksten) bør være koblet til tekstfeltet i koden slik at skjermlesere kan lese opp riktig informasjon. Komplekse skjema kan kreve mer hjelp enn bare enn labels.
  • Feilmeldinger bør være kodet som tekst og identifisere det spesifikke skjemaelementet hvor feilen oppstod. Feilmeldingen må beskrive feilen og være synlig uten at brukeren gjør noen ekstra handlinger.

Sjekkliste

✓ Alle nedtrekksmenyene har tilknyttet label eller instruksjon.

✓ Tydelig, kort og konsis label
