Di-dropdown tša go theoga

Fetoša dikhupetšo tša diteng bakeng sa go bontšha mananeo a dikgokagano le tše dingwe ka polaka ya go theoga ya Bootstrap.

Kakaretšo

Di-dropdown di ka fetošwa, di-overlay tša diteng tša go bontšha mananeo a dikgokagano le tše dingwe. Di dirilwe gore di be le tirišano ka plugin ya JavaScript ya go theoga ya Bootstrap yeo e akareditšwego. Di fetošwa ka go kgotla, e sego ka go hovering; se ke sephetho sa go hlama ka boomo.

Di-dropdown di agilwe godimo ga bokgobapuku bja mokgatlo wa boraro, Popper.js , yeo e fago maemo a go fetoga le go utolla lefelo la go lebelela. Kgonthišetša gore o akaretša popper.min.js pele ga JavaScript ya Bootstrap goba o diriša bootstrap.bundle.min.js/ bootstrap.bundle.jsyeo e nago le Popper.js. Popper.js ga e šomišwe go bea di-dropdown ka go di-navbar le ge e le go beakanya ga go fetoga ga go nyakege.

Ge e ba o aga JavaScript ya rena go tšwa mothopong, e nyakautil.js .

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.
