Suspended filters

Good afternoon! I would like a SUPER HELP, I am new to the internship and I have to make some modifications on the site. I need to make a suspense filter. I already have an example here, but BUT try to play the cod it does not work.

@Html.Partial("_Competencias", new ViewDataDictionary {
 {
  "ExibirRotulo",
  true
 }, {
  "ExibirTodos",
  true
 }, {
  "MaximoSelecionado",
  "5"
 }
})
@if(FiltrosCandidatosConfig.Competencias == "A") {
 @Html.Partial("_Competencias", new ViewDataDictionary {
  {
   "ExibirTodos",
   true
  }
 })
}
