How to create a listbox in HTML without allowing multiple selection?

Question

I don\'t have much experience in HTML. I am looking to create a simple listbox, but one of the requirements is to DISALLOW multiple selection. Most of the code for listboxes

Answer 1

Just use the size attribute:

<select name="sometext" size="5">
  <option>text1</option>
  <option>text2</option>
  <option>text3</option>
  <option>text4</option>
  <option>text5</option>
</select>

To clarify, adding the size attribute did not remove the multiple selection.

The single selection works because you removed the multiple="multiple" attribute.

Adding the size="5" attribute is still a good idea, it means that at least 5 lines must be displayed. See the full reference here

Answer 2

For Asp.Net MVC

@Html.ListBox("parameterName", ViewBag.ParameterValueList as MultiSelectList, 
 new { 
 @class = "chosen-select form-control"
 }) 

or

  @Html.ListBoxFor(model => model.parameterName,
  ViewBag.ParameterValueList as MultiSelectList,
   new{
       data_placeholder = "Select Options ",
       @class = "chosen-select form-control"
   })

Answer 3

Remove the multiple="multiple" attribute and add SIZE=6 with the number of elements you want
