ASP.NET MVC 5 - Generate different forms based on selected DropDownList option

Question

I want to generate (or display hidden maybe?) different type of form depending on the selected Option in a DropDownList. What would be the best way to do that?

I have tried having in the base view named Create only a DropDownList with no forms initially, and script where on change using Ajax to some action in a controller which loads a partial view of the desired form display it as an HTML inside some <div> form container.

The problem with this is that I am not getting any client-side validation on the fields of the newly displayed form.

Javascript/jQuery code from Create view:

let dropDown = $("#SelectedExpenseType")
let expenseFormContainer = $("#ExpenseCreationForm")

dropDown.change(function () {
    let url = dropDown.val();
    //Check if selected option has NULL for Value Attribute
    if ($.isEmptyObject(url)) {
        expenseFormContainer.empty()
        return;
    }
    
    expenseFormContainer.load(url);
})
