Retningslinjer

Bruk med kun placeholdertekst

Ikke bruk den dersom du har få valg

Formatering

Anatomi

1. Label Tekst som informerer bruker om hva de kan forvente å finne i nedtrekksmenyen

2. Beskrivelse Hjelpetekst som gir bruker kontekst for å ta riktig valg i nedtrekksmenyen

3. Dropdown Ekspanderende felt som supplerer hjelpeteksten. Viktig informasjon skal ikke legges her

4. Verdi Viser valget brukeren har tatt i select-komponenten

5. Field Der brukeren legger inn data.

Universell utforming

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
