Use two links inline  Hide the link with the dropdown toggle and add the onmouseover event over the visible link to click the dropdown menu    lt a class  pretty-button     href     alt  Notifications     onmouseover      notifications-dropdown   click    gt   lt  a gt    lt a style  display none     id  notifications-dropdown     class  js-nav js-tooltip js-dynamic-tooltip     href        alt  Notifications     data-toggle  dropdown  gt      lt span class  fa fa-flag fa-2x  gt  lt  span gt   lt  a gt

Here s my technique that adds a slight delay before the menu is closed after you stop hovering on the menu or the toggle button  The  lt button gt  that you would normally click to display the nav menu is  nav dropdown     function       var delay close it  nav menu timeout  open it    nav menu timeout   void 0    open it   function         if  nav menu timeout          clearTimeout nav menu timeout         nav menu timeout   null            return     navbar  dropdown   addClass  open           delay close it   function         var close it      close it   function           return     navbar  dropdown   removeClass  open               return nav menu timeout   setTimeout close it  500             body   on  mouseover     nav dropdown   nav dropdown     open it  on  mouseout     nav dropdown   delay close it     return    body   on  mouseover     navbar  dropdown  dropdown-menu   open it  on  mouseout     navbar  dropdown  dropdown-menu   delay close it

This also can do that       dropdown   on  mouseover  function          this  find   dropdown-menu   show            dropdown   on  mouseleave  function          this  find   dropdown-menu   hide          If the dropdown has a gap between the hovered element the drop down will immediately close as seen in this GIF  To prevent this behaviour you can add a timeout to the events of 100 ms let dropdownTimer      dropdown   on  mouseover        gt        clearTimeout dropdownTimer        this  find   dropdown-menu   show            dropdown   on  mouseleave        gt       dropdownTimer   setTimeout      gt              this  find   dropdown-menu   hide           100

This is probably a stupid idea  but to just remove the arrow pointing down  you can delete the   lt b class  caret  gt  lt  b gt    This does nothing for the up pointing one  though

To get the menu to automatically drop on hover then this can achieved using basic CSS  You need to work out the selector to the hidden menu option and then set it to display as block when the appropriate li tag is hovered over  Taking the example from the twitter bootstrap page  the selector would be as follows   ul nav li dropdown hover  gt  ul dropdown-menu       display  block          However  if you are using Bootstrap s responsive features  you will not want this functionality on a collapsed navbar  on smaller screens   To avoid this  wrap the code above in a media query    media  min-width  979px      ul nav li dropdown hover  gt  ul dropdown-menu       display  block            To hide the arrow  caret  this is done in different ways depending on whether you are using Twitter Bootstrap version 2 and lower or version 3   Bootstrap 3  To remove the caret in version 3 you just need to remove the HTML  lt b class  caret  gt  lt  b gt  from the  dropdown-toggle anchor element    lt a class  dropdown-toggle  data-toggle  dropdown  href     gt      Dropdown      lt b class  caret  gt  lt  b gt      lt -- remove this line  lt  a gt    Bootstrap 2  amp  lower  To remove the caret in version 2 you need a little more insight into CSS and I suggest looking at how the  after pseudo element works in more detail  To get you started on your way to understanding  to target and remove the arrows in the twitter bootstrap example  you would use the following CSS selector and code   a menu after   dropdown-toggle after       content  none      It will work in your favour if you look further into how these work and not just use the answers that I have given you   Thanks to  CocaAkat for pointing out that we were missing the     child combinator to prevent sub menus being shown on the parent hover

So you have this code    lt a class  dropdown-toggle  data-toggle  dropdown  gt Show menu lt  a gt    lt ul class  dropdown-menu  role  menu  gt       lt li gt Link 1 lt  li gt       lt li gt Link 2 lt  li gt        lt li gt Link 3 lt  li gt                                                lt  ul gt    Normally it works on a click event  and you want it work on a hover event  This is very simple  just use this JavaScript jQuery code     document  ready function              dropdown-toggle   mouseover function                 dropdown-menu   show                    dropdown-toggle   mouseout function             t   setTimeout function                     dropdown-menu   hide               100                dropdown-menu   on  mouseenter   function                     dropdown-menu   show                clearTimeout t              on  mouseleave   function                     dropdown-menu   hide                           This works very well and here is the explanation  we have a button  and a menu  When we hover the button we display the menu  and when we mouseout of the button we hide the menu after 100 nbsp ms  If you wonder why I use that  is because you need time to drag the cursor from the button over the menu  When you are on the menu  the time is reset and you can stay there as many time as you want  When you exit the menu  we will hide the menu instantly without any timeout   I ve used this code in many projects  if you encounter any problem using it  feel free to ask me questions

We saw  In addition to the answer from  My Head Hurts    Cory Price  found out two problems      Problem 1  Clicking on the dropdown link will open the dropdown-menu  And it will stay open unless the user clicks somewhere   else  or hovers back over it  creating an awkward UI       Solution  Remove the  class  and  data-toggle  elements from the nav link   The solution was nearly perfect  but the problem here is  when it comes to mobile devices and tablets  it won t work   I m using a bit of jQuery code to fix this    if    window  width    gt  769            dropdown-toggle   removeAttr  data-toggle            dropdown-menu   removeAttr  style            dropdown   removeClass  open        window  resize function          if    window  width    gt  769                dropdown-toggle   removeAttr  data-toggle                dropdown-menu   removeAttr  style                dropdown   removeClass  open              else               dropdown-toggle   attr  data-toggle    dropdown                   Note  Here we assume that the collapse to mobile devices and tablets is from 768px

There are a lot of really good solutions here  But I thought that I would go ahead and put mine in here as another alternative  It s just a simple jQuery snippet that does it the way bootstrap would if it supported hover for dropdowns instead of just click  I ve only tested this with version 3 so I don t know if it would work with version 2  Save it as a snippet in your editor and have it at the stroke of a key    lt script gt        function                 dropdown   hover              function      this  addClass  open                  function      this  removeClass  open                         lt  script gt    Basically  It s just saying when you hover on the dropdown class  it will add the open class to it  Then it just works  When you stop hovering on either the parent li with the dropdown class or the child ul li s  it removes the open class  Obviously  this is only one of many solutions  and you can add to it to make it work on only specific instances of  dropdown  Or add a transition to either parent or child

To enhance Sudharshan s answer  I wrap this in a media query to prevent the hover when on XS display widths      media  min-width 768px        ul nav li dropdown hover  gt  ul dropdown-menu           display  block                  nav  dropdown-menu           margin-top  0            Also the caret in the markup is not required  just the dropdown class for the li

Update  The plugin is on GitHub and I am working on some improvements  like use only with data-attributes  no JS necessary   I ve leaving the code in below  but it s not the same as what s on GitHub   I liked the purely CSS version  but it s nice to have a delay before it closes  as it s usually a better user experience  i e  not punished for a mouse slip that goes 1 px outside the dropdown  etc   and as mentioned in the comments  there s that 1px of margin you have to deal with or sometimes the nav closes unexpectedly when you re moving to the dropdown from the original button  etc   I created a quick little plugin that I ve used on a couple sites and it s worked nicely  Each nav item is independently handled  so they have their own delay timers  etc   JS     outside the scope of the jQuery plugin to    keep track of all dropdowns var  allDropdowns            if instantlyCloseOthers is true  then it will instantly    shut other nav items when a new one is hovered over   fn dropdownHover   function options            the element we really care about        is the dropdown-toggle s parent      allDropdowns    allDropdowns add this parent          return this each function             var  this     this  parent                defaults                     delay  500                  instantlyCloseOthers  true                            data                     delay    this  data  delay                    instantlyCloseOthers    this  data  close-others                              options     extend true      defaults  options  data               timeout            this hover function                 if options instantlyCloseOthers     true                   allDropdowns removeClass  open                 window clearTimeout timeout                 this  addClass  open               function                 timeout   window setTimeout function                      this removeClass  open                   options delay                              The delay parameter is pretty self explanatory  and the instantlyCloseOthers will instantly close all other dropdowns that are open when you hover over a new one   Not pure CSS  but hopefully will help someone else at this late hour  i e  this is an old thread    If you want  you can see the different processes I went through  in a discussion on the  concrete5 IRC  to get it to work via the different steps in this gist  https   gist github com 3876924  The plugin pattern approach is much cleaner to support individual timers  etc   See the blog post for more

I have published a proper plugin for the Bootstrap 3 dropdown hover functionality  in which you can even define what happens when clicking on the dropdown-toggle element  the click can be disabled    https   github com istvan-ujjmeszaros bootstrap-dropdown-hover    Why I made it when there are many solutions already   I had issues with all the previously existing solutions  The simple CSS ones are not using the  open class on the  dropdown  so there will be no feedback on the drop-down toggle element when the drop-down is visible   The js ones are interfering with clicking on  dropdown-toggle  so the dropdown shows up on hover  then hides it when clicking on an opened drop-down  and moving out the mouse will trigger the drop-down to show up again  Some of the js solutions are breaking iOS compatibility  some plugins are not working on modern desktop browsers which are supporting the touch events   That s why I made the Bootstrap Dropdown Hover plugin which prevents all these issues by using only the standard Bootstrap javascript API  without any hack  Even the Aria attributes are working fine with this plugin

In addition to the answer from  My Head Hurts   which was great    ul nav li dropdown hover ul dropdown-menu      display  block          There are 2 lingering issues    Clicking on the dropdown link will open the dropdown-menu  And it will stay open unless the user clicks somewhere else  or hovers back over it  creating an awkward UI  There is a 1px margin between the dropdown link  and dropdown-menu  This causes the dropdown-menu to become hidden if you move slowly between the dropdown and dropdown-menu    The solution to  1  is removing the  class  and  data-toggle  elements from the nav link   lt a href     gt       Dropdown       lt b class  caret  gt  lt  b gt   lt  a gt    This also gives you the ability to create a link to your parent page - which wasn t possible with the default implementation  You can just replace the     with whatever page you want to send the user   The solution to  2  is removing the margin-top on the  dropdown-menu selector   navbar  dropdown-menu       margin-top  0px

If you have an element with a dropdown class like this  for example     lt ul class  list-unstyled list-inline  gt       lt li class  dropdown  gt           lt a data-toggle  dropdown  href     gt  lt i class  fa fa-bars  gt  lt  i gt  Dropdown 1 lt  a gt           lt ul class  dropdown-menu  gt               lt li gt  lt a href    gt Item 1 lt  a gt  lt  li gt               lt li gt  lt a href    gt Item 2 lt  a gt  lt  li gt               lt li gt  lt a href    gt Item 3 lt  a gt  lt  li gt               lt li gt  lt a href    gt Item 4 lt  a gt  lt  li gt               lt li gt  lt a href    gt Item 5 lt  a gt  lt  li gt           lt  ul gt       lt  li gt       lt li class  dropdown  gt           lt a data-toggle  dropdown  href     gt  lt i class  fa fa-user  gt  lt  i gt  Dropdown 2 lt  a gt           lt ul class  dropdown-menu  gt               lt li gt  lt a href    gt Item A lt  a gt  lt  li gt               lt li gt  lt a href    gt Item B lt  a gt  lt  li gt               lt li gt  lt a href    gt Item C lt  a gt  lt  li gt               lt li gt  lt a href    gt Item D lt  a gt  lt  li gt               lt li gt  lt a href    gt Item E lt  a gt  lt  li gt           lt  ul gt       lt  li gt   lt  ul gt    Then you can have the dropdown menu to be automatically drop down on hover over  rather than having to click its title  by using this snippet of jQuery code    lt script gt          dropdown   hover          function                   this  find   dropdown-menu   stop true  true  delay 200  fadeIn                       function                   this  find   dropdown-menu   stop true  true  delay 200  fadeOut                              dropdown-menu   hover          function                   this  stop true  true                      function                   this  stop true  true  delay 200  fadeOut                      lt  script gt    Here is a demo  This answer relied on  Michael answer  I have made some changes and added some additions to get the dropdown menu work properly
