I love the select2 box from https   github com ivaynberg select2 I am using the format  option to format each element  and it looks great   Everything is fine except the selected element is bigger than the height of the select box due to an image   I know how to change the width  but how do I change the height so that AFTER the element is selected  it shows the full thing  about 150px   Here is my initiation    lt script gt          selboxChild   select2           matcher  function term  text                 var t    js child sponsors text    js child sponsors text    text                return t toUpperCase   indexOf term toUpperCase     gt   0                      formatResult  formatChild          formatSelection  formatChild          escapeMarkup  function m                return m                     lt  script gt    and here is my select box   lt select id  selboxChild  style  width  300px  height  200px  gt       lt option value    gt No child attached lt  option gt   lt  select gt    To Clarify  I do NOT want the Height of each option to change I am looking for the select box to change height after you select a child   So when the page first loads it says  No child selected  When you click the drop down and select a child you see the child s image  NOW i need the select box to expand  Otherwise the picture of the child is cut off   Does anyone understand

For v4 0 7 You can increase the height by overriding CSS classes like this example        select2-container  select2-selection--single       height  36px      select2-container--default  select2-selection--single  select2-selection  rendered       line-height  36px      select2-container--default  select2-selection--single  select2-selection  arrow       height  36px

IMHO  setting the height to a fixed number is rarely a useful thing to do  Setting it to whatever space is available on the screen is much more useful   Which is exactly what this code does      select   on  select2-opening   function         var container     this  select2  container       var position     this  select2  container   offset   top     var avail height     window  height   - container offset   top - container outerHeight           The 50 is a magic number here  I think this is the search box   other UI        chrome from select2         ul select2-results   css  max-height    avail height - 50    px       I made this for select2 3 5  I didn t test it with 4 0  but from the documentation is will probably work for 4 0 as well

I had a similar problem  and most of these solutions are close but no cigar  Here is what works in its simplest form    select2-selection       min-height  10px  important      You can set the min-height to what ever you want   The height will expand as needed   I personally found the padding a bit unbalanced  and the font too big  so I added those here also

You don t need to change the height for all select2 - source  lt input gt  classes are being copied to select2-container  so you can style them by classes of inputs  For example if you want to style the height of some instances of select2  add class your-class to source  lt select gt  element and then use   select2-container your-class in your CSS file   Regards   There is some issue  classes name as select2  are not copied

You probably want to give a special class to your select2 first  then modify the css for that class only  rather than changing all select2 css  sitewide        selboxChild   select2   width   300px   dropdownCssClass   bigdrop        SCSS   bigdrop select2-container  select2-results  max-height  200px    bigdrop  select2-results  max-height  200px    bigdrop  select2-choices  min-height  150px  max-height  150px  overflow-y  auto

Seems the stylesheet selectors have changed over time   I m using select2-4 0 2 and the correct selector to set the box height is currently    select2-container--default  select2-results  gt   select2-results  options       max-height  200px

User · Answer

You could do this with some simple css  From what I read  you want to set the Height of the element with the class  select2-choices     select2-choices     min-height  150px    max-height  150px    overflow-y  auto      That should give you a set height of 150px and it will scroll if needed  Simply adjust the height till your image fits as desired   You can also use css to set the height of the select2-results  the drop down portion of the select control    ul select2-results    max-height  200px      200px is the default height  so change it for the desired height of the drop down
