Phihlelelo

The WAI ARIA standard defines an actual role="menu"widget , eupša se se itšego go dimenu tša go swana le tirišo tšeo di hlohleletšago ditiro goba mešomo. Dimenu tša ARIA di ka ba le fela diaetheme tša thepo, diaetheme tša thepo ya lepokisi la go hlahloba, diaetheme tša thepo ya konope ya radio, dihlopha tša dikonope tša radio, le dimenu tša ka fasana.

Di-dropdown tša Bootstrap, ka lehlakoreng le lengwe, di hlamilwe go ba tša kakaretšo le go šoma maemong a fapa-fapanego le dibopego tša go swaya. Go fa mohlala, go a kgonega go hlama dithepo te di theogago te di nago le ditseno ta tlaleleto le ditaolo ta diforomo, go swana le mafelo a go nyaka goba diforomo ta go tsena. Ka lebaka le, Bootstrap ga e letele (goba go oketša ka go iketla) efe goba efe ya rolele aria-dika tše di nyakegago bakeng sa dimenu tša nnete tša ARIA . Bangwadi ba tla swanelwa ke go akaretša dika tše tše di lebanyago kudu ka bobona.

Le ge go le bjalo, Bootstrap e tlaleletša thekgo ye e agetšwego ka gare ya bontši bja ditirišano tša thepo ya khiiboto ya maemo, go swana le bokgoni bja go sepela ka .dropdown-itemdielemente ka botee ka go šomiša dinotlelo tša khesara le go tswalela thepo ka ESCsenotlelo.
