Mekhoa

E kenya tšebetsong litaba tsa hau joalo ka ntho e ka putlamang. E amohela khetho ea boikhethelo object.

O ka etsa mohlala oa ho putlama le moetsi, mohlala:

var myCollapse = document.getElementById('myCollapse')
var bsCollapse = new bootstrap.Collapse(myCollapse, {
  toggle: false
})

Liketsahalo
