I'm developing a site in Umbraco 7. Added "Umbraco Forms" for a basic comment functionality.

However once posted the form disappears and shows the "thank you" message. I want the form to still be there so they can post another if they want to without refreshing the page.

Looking at /Views/Partials/Forms/Form.cshtml

It starts with

@if (Model.SubmitHandled)
{
    if (Model.RenderMode == "full" || Model.RenderMode == "form")
    {
        <p class="contourMessageOnSubmit">@Html.Raw(Model.MessageOnSubmit)</p>
        <p>Add another</p>
    }
} else {

So we get rid of the else bit, add in an extra @ or two because - well we all know razor is a bit of a dick

And error....

Line 142 is

foreach (var script in Model.CurrentPage.JavascriptFiles)

Of section

 @if (Model.RenderMode == "full" || Model.RenderMode == "script")
{
    @Html.Partial(FormViewResolver.GetScriptView(Model.FormId), Model)

    foreach (var script in Model.CurrentPage.JavascriptFiles)
    {
        if (Model.UseClientDependency)
        {
            Html.RequiresJs(script.Value);
        }
        else
        {

        }
    }

    if (Model.CurrentPage.JavascriptCommands.Count > 0)
    {

        <script type="text/javascript">
            @foreach (var cmd in Model.CurrentPage.JavascriptCommands)
            {
                <text>@Html.Raw(cmd)</text>
            }

        </script>
    }

    foreach (var css in Model.CurrentPage.CssFiles)
    {
        if (Model.UseClientDependency)
        {
            Html.RequiresCss(css.Value);
        }
        else
        {
            <link rel="stylesheet" href="@Url.Content(css.Value)" />
        }
    }

}

Any ideas?
