I am very new to umbraco and I wanted to make the parent of my submenus to be static (#) if the doctype used has no template, so far these are what I have done.

                                    if (root != null)
                                    {
                                        foreach (var child in root.Children)
                                        {
                                            <li class="menu-item menu-item-type-custom menu-item-object-custom menu-item-5818 @(Model.Url == child.Url ? "current-menu-item" : null)" style="display: flex; justify-content: space-between">
                                                <a href="@child.Url">@child.Name</a>
                                                @if (child.Children.Any() && !child.IsDocumentType("people"))
                                                {
                                                    <button href="#" onclick="toggleChildMenu('child-@child.Id', this)" style="cursor: pointer; background: none; border: none; padding: 0 1rem; font-size: 1rem; color: rgb(140, 140, 140)">
                                                        <i class="fa fa-chevron-down" aria-hidden="true"></i>
                                                    </button>
                                                }
                                            </li>
                                            if (child.Children.Any() && !child.IsDocumentType("people")) // don't show child nodes of people
                                            {
                                                <li id="child-@child.Id" style="border: none; display: none;">
                                                    <ul style="margin-left: 1rem; margin-bottom: 0;" class="gdlr-core-custom-menu-widget gdlr-core-menu-style-list">
                                                        @foreach (var child2 in child.Children)
                                                        {
                                                            <li class="menu-item menu-item-type-custom menu-item-object-custom menu-item-5818 @(Model.Url == child2.Url ? "current-menu-item" : null)">
                                                                <a href="@child2.Url">@child2.Name</a>
                                                            </li>
                                                        }
                                                    </ul>
                                                </li>
                                            }
                                        }
                                    }
                                }
