Right-to-Left Support
The Navigation widgets fully support RTL languages. As is illustrated in this demo, the Navigation widgets are able to display their contents in a right-to-left direction and fully mirror associated UI elements. Use the language drop-down menu (change from English to Arabic) to explore the differences between default and RTL modes available in DevExtreme.
window.onload = function() {
var languages = [
"Arabic: Right-to-Left direction",
"English: Left-to-Right direction"
];
var rtlEnabled = ko.observable(false);
var accordionTemplate = ko.computed(function() {
return rtlEnabled() ? "arabic" : "english";
});
var accordionTitleTemplate = ko.computed(function() {
return rtlEnabled() ? "arabicTitle" : "englishTitle";
});
var displayExpr = ko.computed(function() {
return rtlEnabled() ? "textAr" : "text";
});
var viewModel = {
rtlEnabled: rtlEnabled,
treeViewOptions: {
dataSource: continents,
width: 200,
displayExpr: displayExpr,
rtlEnabled: rtlEnabled
},
menuOptions: {
dataSource: continents,
rtlEnabled: rtlEnabled,
displayExpr: displayExpr
},
accordionOptions: {
dataSource: europeCountries,
itemTitleTemplate: accordionTitleTemplate,
itemTemplate: accordionTemplate,
rtlEnabled: rtlEnabled,
},
selectBoxOptions: {
items: languages,
value: languages[1],
onValueChanged: function(data) {
rtlEnabled(data.value === languages[0]);
}
}
};
ko.applyBindings(viewModel, document.getElementById("rtl"));
};
