Custom markup

    With Umbraco Forms it's possible to customize the outputted markup of a form, which means you have complete control over what Forms will output.

    When using Forms version 6 or higher, we strongly recommend that you use Themes when you want to customize your forms. This will ensure that nothing is overwritten when you upgrade Forms to a newer version.

    Customizing the default views

    The way the razor macro works is that it uses some razor views to output the form:

    • 1 view for each fieldtype
    • 1 view for the scripts
    • 1 view for the rest of the form

    You can find the default views in the ~\Views\Partials\Forms\Themes\default folder if you are using Forms 6+, or in the ~\Views\Partials\Forms\folder if you are using Forms 4.

    To avoid that your custom changes to the default views are overwritten you need to copy the view you want to customize into your theme folder, e.g. ~\Views\Partials\Forms\Themes\YourTheme, and edit it there.


    This is the main view responsible for rendering the form markup.

    The view is separated into two parts, one is the actual form and the other will be shown if the form is submitted.

    This view can be customized, if you do so it will be customized for all your forms.


    This view renders the JavaScript that will take care of the conditional logic, customization won't be needed here.


    The rest of the views start with FieldType, like FieldType.Textfield.cshtml and those will output the fields. There is a view for each default fieldtype like textfield, textarea, checkbox, etc)

    Contents of the FieldType.Textfield.cshtml view (from the default theme):

    @model Umbraco.Forms.Mvc.Models.FieldViewModel
    @using Umbraco.Forms.Mvc
    <input type="text" 
        class="@Html.GetFormFieldClass(Model.FieldTypeName) text" 
        @{if(string.IsNullOrEmpty(Model.PlaceholderText) == false){<text>placeholder="@Model.PlaceholderText"</text>}}
        @{if(Model.Mandatory || Model.Validate){<text>data-val="true"</text>}}
        @{if (Model.Mandatory) {<text> data-val-required="@Model.RequiredErrorMessage"</text>}}
        @{if (Model.Validate) {<text> data-val-regex="@Model.InvalidErrorMessage" data-regex="@Html.Raw(Model.Regex)"</text>}}

    By default the form makes use of jQuery validate and jQuery validate unobtrusive which is why you see attributes like data-val and data-val-required.

    This can be customized but it's important to keep the ID of the control to @Model.Id since that is used to match the value to the form field.

    Customizing for a specific form

    In Forms 4 it is also possible to customize the markup for a specific form.

    You will need to create folder using the ID of the form: ~\Views\Partials\Forms\{FormId} (find the id of the form in the URL when you are viewing the form in the backoffice.)

    Form GUID

    As an example if your form ID is 0d3e6b2d-db8a-43e5-8f28-36241d712487 then you can overwrite the form view by adding the Form.cshtml file to the directory. Start by copying the default one and then making your custom changes: ~\Views\Partials\Forms\0d3e6b2d-db8a-43e5-8f28-36241d712487\Form.cshtml.

    You can also overwrite views for one or more fieldtypes by adding the views to the folder: ~\Views\Partials\Forms\0d3e6b2d-db8a-43e5-8f28-36241d712487\Fieldtype.Textfield.cshtml.
