Avoid dropdown menu close on click inside

Question

I have a Twitter Bootstrap dropdown menu  As all Twitter Bootstrap users know  the dropdown menu closes on click  even clicking inside it    To avoid this  I can easily attach a click event handler on the dropdown menu and simply add the famous event stopPropagation       lt ul class  nav navbar-nav  gt     lt li class  dropdown mega-dropdown  gt       lt a href  javascript    class  dropdown-toggle  data-toggle  dropdown  gt         lt i class  fa fa-list-alt  gt  lt  i gt  Menu item 1        lt span class  fa fa-chevron-down pull-right  gt  lt  span gt       lt  a gt       lt ul class  dropdown-menu mega-dropdown-menu  gt         lt li gt           lt div id  carousel  class  carousel slide  data-ride  carousel  gt             lt ol class  carousel-indicators  gt               lt li data-slide-to  0  data-target   carousel  gt  lt  li gt               lt li class  active  data-slide-to  1  data-target   carousel  gt  lt  li gt             lt  ol gt             lt div class  carousel-inner  gt               lt div class  item  gt                 lt img alt    class  img-rounded  src  img1 jpg  gt               lt  div gt               lt div class  item active  gt                 lt img alt    class  img-rounded  src  img2 jpg  gt               lt  div gt             lt  div gt             lt a data-slide  prev  role  button  href   carousel                class  left carousel-control  gt               lt span class  glyphicon glyphicon-chevron-left  gt  lt  span gt             lt  a gt             lt a data-slide  next  role  button  href   carousel                class  right carousel-control  gt               lt span class  glyphicon glyphicon-chevron-right  gt  lt  span gt             lt  a gt           lt  div gt         lt  li gt       lt  ul gt     lt  li gt   lt  ul gt    This looks easy and a very common behavior  however  and since carousel-controls  as well as carousel indicators  event handlers are delegated to the document object  the click event on these elements  prev next controls       will be    ignored         ul dropdown-menu mega-dropdown-menu   on  click   function event          The event won t be propagated up to the document NODE and         therefore delegated events won t be fired     event stopPropagation          Relying on Twitter Bootstrap dropdown hide hidden events is not a solution for the following reasons    The provided event object for both event handlers does not give reference to the clicked element I don t have control over the dropdown menu content so adding a flag class or attribute is not possible   This fiddle is the normal behavior and this fiddle is with event stopPropagation   added   Update  Thanks to Roman for his answer  I also found an answer that you can find below

I know this question was specifically for jQuery  but for anyone using AngularJS that has this problem you can create a directive that handles this       angular module  app   directive  dropdownPreventClose   function         return           restrict   A           link  function scope  element  attrs              element on  click   function e                e stopPropagation      prevent the default behavior of closing the dropdown-menu                                      Then just add the attribute dropdown-prevent-close to your element that is triggering the menu to close  and it should prevent it   For me  it was a select element that automatically closed the menu    lt div class  dropdown-menu  gt     lt select dropdown-prevent-close name  myInput  id  myInput  ng-model  myModel  gt       lt option value    gt Select Me lt  option gt     lt  select gt   lt  div gt

The simplest working solution for me is    adding keep-open class to elements that should not cause dropdown closing and this piece of code do the rest        dropdown   on  click   function e        var target     e target       var dropdown   target closest   dropdown        return  dropdown hasClass  open       target hasClass  keep-open

I ve got a similar problem recently and tried different ways to solve it with removing the data attribute data-toggle  dropdown  and listening click with event stopPropagation   calling   The second way looks more preferable  Also Bootstrap developers use this way  In the source file I found initialization of the dropdown elements      APPLY TO STANDARD DROPDOWN ELEMENTS   document   on  click bs dropdown data-api   clearMenus   on  click bs dropdown data-api     dropdown form   function  e    e stopPropagation       on  click bs dropdown data-api   toggle  Dropdown prototype toggle   on  keydown bs dropdown data-api   toggle  Dropdown prototype keydown   on  keydown bs dropdown data-api     dropdown-menu   Dropdown prototype keydown    jQuery     So  this line    on  click bs dropdown data-api     dropdown form   function  e    e stopPropagation        suggests you can put a form element inside the container with class  dropdown to avoid closing the dropdown menu

Bootstrap has solved this problem themselves in their support for  lt form gt  tags in dropdowns  Their solution is quite graspable and you can read it here  https   github com twbs bootstrap blob v4-dev js src dropdown js  It boils down to preventing propagation at the document element and doing so only for events of type  click bs dropdown data-api  that match the selector   dropdown  your-custom-class-for-keep-open-on-click-elements    Or in code    document  on  click bs dropdown data-api     dropdown  keep-open-on-click    event    gt        event stopPropagation

The absolute best answer is to put a form tag after the class dropdown-menu  so your code is   lt ul class  dropdown-menu  gt     lt form gt       lt li gt         lt div class  menu-item  gt bla bla bla lt  div gt       lt  li gt     lt  form gt   lt  ul gt

You could simply execute event stopPropagation on click event of the links themselves  Something like this           dropdown-menu a   click  event    gt             event stopPropagation            let url   event target href            Do something with the url or any other logic you wish          Edit  If someone saw this answer and is using react  it will not work  React handle the javascript events differently and by the time your react event handler is being called  the event has already been fired and propagated  To overcome that you should attach the event manually like that  handleMenuClick event       event stopPropagation      let menu item   event target      implement your logic here    componentDidMount         document getElementsByClassName  dropdown-menu   0  addEventListener           click   this handleMenuClick bind this   false

Bootstrap provides the following function                      This event is fired immediately when the hide instance method  hide bs dropdown   has been called  The toggling anchor element is available as the                     relatedTarget property of the event   Therefore  implementing this function should be able to disable the dropdown from closing       myDropdown   on  hide bs dropdown   function  e        var target     e target       if target hasClass  keepopen      target parents   keepopen   length           return false     returning false should stop the dropdown from hiding       else          return true

Removing the data attribute data-toggle  dropdown  and implementing the open close of the dropdown can be a solution   First by handling the click on the link to open close the dropdown like this       li dropdown mega-dropdown a   on  click   function  event          this  parent   toggleClass  open          and then listening the clicks outside of the dropdown to close it like this       body   on  click   function  e        if      li dropdown mega-dropdown   is e target            amp  amp     li dropdown mega-dropdown   has e target  length     0           amp  amp      open   has e target  length     0                    li dropdown mega-dropdown   removeClass  open                Here is the demo   http   jsfiddle net RomaLefrancois hh81rhcm 2

You may have some problems if you use return false or stopPropagation   method because your events will be interrupted  Try this code  it s works fine     function             dropdown   on  click   function  e                    keep-open   removeClass  show                    dropdown-toggle   on  click   function                      keep-open   addClass  show                      closeDropdown    click function                 dropdown   closeDropdown                jQuery fn extend       closeDropdown  function             this addClass  show                removeClass  keep-open                click                addClass  keep-open                  In HTML    lt div class  dropdown keep-open  id  search-menu   gt       lt button  class  btn dropdown-toggle btn  btn-primary  type  button  data-toggle  dropdown  aria-haspopup  true  aria-expanded  false  gt       lt i class  fa fa-filter fa-fw  gt  lt  i gt        lt  button gt       lt div class  dropdown-menu  gt           lt button class  dropdown-item  id  opt1  type  button  gt Option 1 lt  button gt           lt button class  dropdown-item  id  opt2  type  button  gt Option 2 lt  button gt           lt button type  button  class  btn btn-primary closeDropdown  gt Close lt  button gt       lt  div gt   lt  div gt    If you want to close the dropdrown        search-menu   closeDropdown

With Angular2 Bootstrap  you can use nonInput for most scenarios    lt div dropdown autoClose  nonInput  gt       nonInput -  default  automatically closes the dropdown when any of its elements is clicked     as long as the clicked element is not an input or a textarea    https   valor-software com ng2-bootstrap   dropdowns

You can stop click on the dropdown from propagating and then manually reimplement the carousel controls using carousel javascript methods      ul dropdown-menu mega-dropdown-menu   on  click   function event        event stopPropagation            a left   click function              carousel   carousel  prev            a right   click function              carousel   carousel  next            ol carousel-indicators li   click function  event        var index     this  data  slide-to            carousel   carousel index         Here is the jsfiddle

Instead of writing some javascript or jquery code reinventing the wheel   The above scenario can be managed by bootstrap auto-close option  You can provide either of the values to auto-close    always -  Default  automatically closes the dropdown when any of its elements is clicked  outsideClick - closes the dropdown automatically only when the user clicks any element outside the dropdown  disabled - disables the auto close   Take a look at the following plunkr    http   plnkr co edit gnU8M2fqlE0GscUQtCWa p preview  Set  uib-dropdown auto-close  disabled     Hope this helps

In  dropdown content put the  keep-open class on any label like so       dropdown   on  click   function  e        var target     e target       var dropdown   target closest   dropdown        if  target hasClass  keep-open                dropdown  addClass  keep-open          else             dropdown  removeClass  keep-open                 document  on  hide bs dropdown   function  e        var target     e target       if    target  is   keep-open              return false             The previous cases avoided the events related to the container objects  now  the container inherits the class keep-open and check before being closed

I modified  Vartan s answer to make it work with Bootstrap 4 3  His solution doesn t work anymore with the latest version as target property always returns dropdown s root div no matter where the click was placed    Here is the code       dropdown-keep-open   on  hide bs dropdown   function  e      if   e clickEvent           There is no  clickEvent  property in the  e  object when the  button   or any other trigger  is clicked          What we usually want to happen in such situations is to hide the dropdown so we let it hide       return true         var target     e clickEvent target      return   target hasClass  dropdown-keep-open      target parents   dropdown-keep-open   length          lt div class  dropdown dropdown-keep-open  gt     lt button class  btn btn-secondary dropdown-toggle  type  button  id  dropdownMenuButton  data-toggle  dropdown  aria-haspopup  true  aria-expanded  false  gt      Dropdown button    lt  button gt     lt div class  dropdown-menu  aria-labelledby  dropdownMenuButton  gt       lt a class  dropdown-item  href     gt Action lt  a gt       lt a class  dropdown-item  href     gt Another action lt  a gt       lt a class  dropdown-item  href     gt Something else here lt  a gt     lt  div gt   lt  div gt
