Downdown menu

I made a menu for umbraco but I can't get the dropdown to work! Below is my code:

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage

                    <div class="NavDigiCampuz">
                        <div>
                            <div class="nav nav-list tree">
                                @{                                  
                                    var documentRootNodeId = Model.Content.GetPropertyValue("documentRoot", true); // Fetch recursive document root id.
                                    var selection = Umbraco.TypedContent(documentRootNodeId).Children.Where("Visible"); // Select all nodes below the document root.
                                }

                                @foreach(var item in Model.Content.Ancestor(1).Descendants("menu")){
                                    foreach (var Menus in @item.Descendants("menuItem")){
                                        <li class="MenuItems">@Menus.Name</li>  
                                            foreach (var MenuItems in @Menus.Children){
                                                if(MenuItems.GetPropertyValue("hoofdstukIcoon") != "") {
                                                <li><a class="NormalA" href="@MenuItems.Url"><i class="fa fa-@(MenuItems.GetPropertyValue("hoofdstukIcoon")) fa-fw"></i> @MenuItems.Name</a></li>
                                                    }else {
                                                            <li><a class="NormalA"href="@MenuItems.Url">@MenuItems.Name</a></li>



                                                var childIsActive = false;

                                                    foreach(var sub in @MenuItems.Children){
                                                    if (CurrentPage.Url == sub.Url) {
                                                        childIsActive = true;
                                                    }



                                            <ul class="nav subnav nav-list tree @(childIsActive ? "" : "collapse")">
                                                @foreach(var sub2 in @MenuItems.Children){
                                                    <li @(CurrentPage.Url == sub.Url ? "class=active" : "")>
                                                        <a onclick="parent.resizeParent();" href="@sub.Url">@(sub.GetPropertyValue("hoofdstukMenuTitel") != "" ? sub.GetPropertyValue("hoofdstukMenuTitel") : sub.GetPropertyValue("hoofdstukTitel"))</a>
                                                    </li>
                                                }
                                            </ul>
                                            }
                                        }
                                    }
                                }
                                }
                            </ul>
                            </div>
                        </div>
                    </div>

The dropdown code should start at <ul class="nav subnav nav-list tree @(childIsActive ? "" : "collapse")"> but that doesn't seem to work.

Below is a quick structure of how I want my page to be:

Help item 3 should have a dropdown which it doesn't have right now. What am I missing?+

Careful with your razor @ tags...

I think you need to correct
```
@foreach(var sub2 in @MenuItems.Children){
```
To
```
@foreach(var sub2 in MenuItems.Children){
```
Also
```
foreach (var Menus in @item.Descendants("menuItem")){
```
should probably be
```
@foreach (var Menus in item.Descendants("menuItem")){
```
The general rule of thumb is you need only an '@' when you are "out" of what I call "razor mode". This is usually when you're not in a @{ } block or when you have opened some HTML tag.. then razor is only expecting more HTML until you say @[HEREISSOMERAZOR] either with a @ { } block or as you're doign with inline @(somevariable.GetPropertyValue<...)

If you're already in "razor mode" then you don't need @ signs in fact it just tends to cause weird bugs e.g. for variables and the like.

I hope that makes sense.

Thanks for the answer! Both unfortunately did not give me a dropdown box. The second foreach should be without the @ because it errors on that. Thanks for trying to help out though!

hi,

Rereading your post - you expect a dropdown why? You're outputting html for a list so unless you have some JS that runs on the page or some CSS that styles it heavily it's always going to look like a sublist?!?

To make a dropdown you need to output some markup like:
```
<select>
  <option value="volvo">Volvo</option>
  <option value="saab">Saab</option>
  <option value="mercedes">Mercedes</option>
  <option value="audi">Audi</option>
</select>
```
