use  empty        select   empty   append  whatever      you can also use  html   but note      When  html   is used to set an element s content  any content that was in that    element is completely replaced by the new content  Consider the following HTML    alternative   --- If you want only option elements to-be-remove  use  remove       select option   remove

You may have select option values such as  Choose option   If you want to keep that value and clear the rest of the values you can first remove all the values and append  Choose Option    lt select multiple  multiple  id  selectName  gt        lt option selected disabled gt Choose Option lt  option gt       lt option gt 1 lt  option gt        lt option gt 2 lt  option gt        lt option gt 3 lt  option gt       lt  select gt    Jquery      selectName option   remove       clear all values      selectName    append   lt option selected disabled gt Choose Option lt  option gt       append what you want to keep

Assuming a list like below - and assuming some of the options were selected      this is a multi select  but this will also work on a single select    lt select multiple  multiple  id  selectListName  gt        lt option gt 1 lt  option gt        lt option gt 2 lt  option gt        lt option gt 3 lt  option gt        lt option gt 4 lt  option gt   lt  select gt    In some function called based on some event  the following code would clear all selected options       selectListName   prop  selectedIndex   -1
