If you use jquery mobile popup you must rewrite _handleDocumentFocusIn function:

_x000D_

$.mobile.popup.prototype._handleDocumentFocusIn = function(e) {_x000D_
  if ($(e.target).closest('.select2-dropdown').length) return true;_x000D_
}

_x000D_

I had the same issue  updating z-index for  select2-container should do the trick  Make sure your modal s z-index is lower than select2 s    select2-container       z-index  99999      Updated  In case above code doesn t work properly  also remove tabindexes from your modal as   breq suggested

For Select2 v4   Use dropdownParent to attach the dropdown to the modal dialog  rather than the HTML body     lt  -- Modal -- gt   lt div class  modal fade  id  myModal  tabindex  -1  role  dialog  aria-labelledby  myModalLabel  gt     lt div class  modal-dialog  role  document  gt       lt div class  modal-content  gt         lt div class  modal-header  gt           lt button type  button  class  close  data-dismiss  modal  aria-label  Close  gt  lt span aria-hidden  true  gt  amp times  lt  span gt  lt  button gt           lt h4 class  modal-title  id  myModalLabel  gt Modal title lt  h4 gt         lt  div gt         lt div class  modal-body  gt           lt select id  select2insidemodal  multiple  multiple  gt             lt option value  AL  gt Alabama lt  option gt                             lt option value  WY  gt Wyoming lt  option gt           lt  select gt         lt  div gt         lt div class  modal-footer  gt           lt button type  button  class  btn btn-default  data-dismiss  modal  gt Close lt  button gt           lt button type  button  class  btn btn-primary  gt Save changes lt  button gt         lt  div gt       lt  div gt     lt  div gt   lt  div gt     lt script gt     document  ready function           select2insidemodal   select2       dropdownParent      myModal               lt  script gt    This will attach the Select2 dropdown so it falls within the DOM of the modal rather than to the HTML body  the default   See https   select2 org dropdown dropdown-placement

I solved this generally in my project by overloading the select2-function   Now it will check if there is no dropdownParent and if the function is called on an element that has a parent of the type div modal   If so  it will add that modal as the parent for the dropdown   This way  you don t have to specify it every time you create a select2-input-box    function        var oldSelect2   jQuery fn select2      jQuery fn select2   function             const modalParent   jQuery this  parents  div modal   first            if  arguments length     0  amp  amp  modalParent length  gt  0                arguments     dropdownParent  modalParent              else if  arguments length     1                      amp  amp  typeof arguments 0       object                       amp  amp  typeof arguments 0  dropdownParent      undefined                       amp  amp  modalParent length  gt  0                arguments 0  dropdownParent   modalParent                    return oldSelect2 apply this arguments                 Copy all properties of the old function to the new     for  var key in oldSelect2            jQuery fn select2 key    oldSelect2 key

Just to understand better how tabindex elements works to complete accepted answer       The tabindex global attribute is an integer indicating if the element can take input focus  is focusable   if it should participate to sequential keyboard navigation  and if so  at what position  It can take several values     nbsp  nbsp -a negative value means that the element should be focusable  but should not be reachable via sequential keyboard navigation        nbsp  nbsp -0 means that the element should be focusable and reachable via sequential keyboard navigation  but its relative order is defined by the platform convention        nbsp  nbsp -a positive value means should be focusable and reachable via sequential keyboard navigation  its relative order is defined by the value of the attribute  the sequential follow the increasing number of the tabindex  If several elements share the same tabindex  their relative order follows their relative position in the document    from   Mozilla Devlopper Network

According to the official select2 documentation this issue occurs because Bootstrap modals tend to steal focus from other elements outside of the modal   By default Select2 attaches the dropdown menu to the  element and it is considered  outside of the modal    Instead attach the dropdown to the modal itself with the dropdownParent setting       myModal   select2      dropdownParent      myModal         See reference  https   select2 org troubleshooting common-problems

I found a solution to this on github for select2 https   github com ivaynberg select2 issues 1436 For bootstrap 3  the solution is    fn modal Constructor prototype enforceFocus   function        Bootstrap 4 renamed the enforceFocus method to  enforceFocus  so you ll need to patch that instead    fn modal Constructor prototype  enforceFocus   function        Explanation copied from link above   Bootstrap registers a listener to the focusin event which checks whether the focused element is either the overlay itself or a descendent of it - if not it just refocuses on the overlay  With the select2 dropdown being attached to the body this effectively prevents you from entering anything into the the textfield  You can quickfix this by overwriting the enforceFocus function which registers the event on the modal
