I’m trying to dropdown html

Question

I’m trying to implement a DropDownList in a View mine that serves for form, but I need the selected value to go to a ViewBag. This is my View there where it is "Car Selected", I would need to turn my Textbox in a DropDownList:

That’s the code of my view:

<div class="form-group">
     <label for="carro" class="col-sm-2 control-label">Carro selecionado</label>
         <div class="col-sm-10">
           <input type="number" class="form-control" id="carro" name="carro" required>
         </div>
</div>

This is my Controller:

public ActionResult FormData()
{
    ViewBag.Veiculo = veiculoDAO.Lista();
    return View();
}

Change your structures to these:

Html

<div class="form-group">
    <label for="carro" class="col-sm-2 control-label">Carro selecionado</label>
    <div class="col-sm-10">
        @Html.DropDownList("Veiculo")
    </div>
</div>

Code

public ActionResult FormData()
{
    var campoId = "nome do campo";
    var campoDescricao = "nome do campo Descricao"  
    ViewBag.Veiculo = new SelectList(veiculoDAO.Lista(), campoId , campoDescricao);
    return View();
}
