点击建议时阻止最新的Twitter类型关闭？

Question

Before flagging this question as duplicate please note I've checked out all of these links and none work with the latest version v0.11.1:

• https://github.com/twitter/typeahead.js/issues/731
• Prevent typeahead.js dropdown from closing on select
• How to prevent Twitter typeahead from filling in the input with the selected value?
• Prevent typeahead dataset from closing on click

My typeahed contains a form with an input. I need to not to close the dropdown when user click a suggestion.

Is there a reliable way to prevent close? The obvious way it's not working ( https://jsfiddle.net/gcgdqfxp/ ):

$('.typeahed').on('typeahead:select', function (event, obj) {
    // not working
    event.preventDefault();

    // not working
    return false;
});

typeahead:select – Fired when a suggestion is selected. The event handler will be invoked with 2 arguments: the jQuery event object and the suggestion object that was selected.

Yeah!!! Found a solution looking at the source here the (undocumented) "typeahead:beforeselect" event is triggered before actually trigger the "typeahead:select", so it's easy to stop propagation ( https://jsfiddle.net/gcgdqfxp/2/ ) like:

$('.typeahead').bind('typeahead:beforeselect', function (event) {
    event.preventDefault();
});
