Issue with Firefox browser: Arrow keys do not function properly for input tags in Twitter Bootstrap drop down menu

Requirement

I need to include a login form inside the dropdown menu with username and password fields. Everything is working fine, except for one issue:

Issue

When typing, I am unable to use the arrow keys (up/down) in Firefox. This functionality works perfectly when the input field is outside the dropdown code. However, it works flawlessly on other browsers like Google Chrome.

  • Firefox version: 26
  • Bootstrap version: 3.03
  • jQuery: 1.10

Question:

How can I resolve this problem? Could the issue be related to jQuery or Twitter's JavaScript, considering it functions properly when I move the input field outside the dropdown?

Answer №1

Seems to be a bug in the code, but you can easily fix it by preventing propagation of the onkeydown event:

Check out the demo here

$('#email').on('keydown',function(e){
    e.stopPropagation();
});
