thanks in advance!

you need clone existing select , append container, keeping count. can utilize number of options in original select restrict number of new ones. also, importantly have create sure give unique id each new select create.

something on lines of this:

class="snippet-code-js lang-js prettyprint-override">var total; // auto limit based on number of options // total = $("#nativelangdrop").find("option").length - 1; // hard code limit total = 5; $("#addbtn").on("click", function() { var ctr = $("#additional").find(".extra").length; if (ctr < total) { var $ddl = $("#nativelangdrop").clone(); $ddl.attr("id", "ddl" + ctr); $ddl.addclass("extra"); $("#additional").append($ddl); } }); class="snippet-code-html lang-html prettyprint-override"><script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <select id="nativelangdrop"> <option value="1">language 1</option> <option value="2">language 2</option> <option value="3">language 3</option> <option value="4">language 4</option> </select> <span id="additional"></span> <hr /> <input id="addbtn" type="button" value=" + " />
