Put input inside select

Answer 1

We can achive it putting the input tag "next to" and not "inside" the select tag but forcing them into a limited and fixed area like a table td.

function selection(){
	var selected=document.getElementById("select1").value;
  if(selected==0){
  	document.getElementById("input1").removeAttribute("hidden");
  }else{
  	//elsewhere actions
  }
}

td{
  width: 170px;
  max-width: 170px;
  overflow: hidden;
  white-space: nowrap;
}

input{
  width: 164px;
}

  

      

        
        
          
          -make your own choice-
          choice 1
          choice 2
