Żgura korretta `role`u ipprovdi tikketta

Sabiex it-teknoloġiji ta' assistenza (bħal screen readers) iwasslu li serje ta' buttuni hija raggruppata, rolejeħtieġ li jiġi pprovdut attribut xieraq. Għal gruppi ta' buttuna, dan ikun role="group", filwaqt li toolbars għandu jkollhom role="toolbar".

Barra minn hekk, gruppi u toolbars għandhom jingħataw tikketta espliċita, peress li l-biċċa l-kbira tat-teknoloġiji ta 'assistenza inkella ma jħabbruhomx, minkejja l-preżenza tal-attribut tar-rwol korrett. Fl-eżempji pprovduti hawn, nużaw aria-label, iżda alternattivi bħal aria-labelledbyjistgħu jintużaw ukoll.

Għaqqad settijiet ta 'gruppi ta' buttuna f'toolbars ta 'buttuni għal komponenti aktar kumplessi. Uża klassijiet ta 'utilità kif meħtieġ biex tispazja gruppi, buttuni, u aktar.

<div class="btn-toolbar" role="toolbar" aria-label="Toolbar with button groups">
  <div class="btn-group mr-2" role="group" aria-label="First group">
    <button type="button" class="btn btn-secondary">1</button>
    <button type="button" class="btn btn-secondary">2</button>
    <button type="button" class="btn btn-secondary">3</button>
    <button type="button" class="btn btn-secondary">4</button>
