showAllValues not working

[jbepure]

What could be the issue ?

this is the code:

accessibleAutocomplete({
// container element
element: document.querySelector('#oras'),
// input id
showAllValues: true,
placeholder: 'alege oras',
id: 'oras',
// data source
source: '#oras',
displayMenu: 'inline'
})
// use select box
accessibleAutocomplete.enhanceSelectElement({
selectElement: document.querySelector('#oras')
})
