嗨Iam用silverstripe創建網站並嘗試使用引導手風琴創建動態sidenav，我已經使用$ Pos創建了id和data-parent屬性的唯一值。Silverstripe Bootstrap Accordion Sidebar
由於$ Pos正在重置，因此我遇到了與列表中的前一項具有相同ID和數據父值的第三級項目的問題。
我的代碼如下：
<div id="extra-links-section" class="extra-nav">
<div class="list-group panel">
<% loop Menu(4) %>
<a class="$LinkingMode list-group-item list-group-item-success" href="<% if $Children && URLSegment != 'coaches-and-managers' %>#dropdown$Pos<% else %>$Link<% end_if %>" <% if $Children && URLSegment != 'coaches-and-managers' %>data-toggle="collapse"<% end_if %> data-parent="#extra-links-section">$Title <% if $Children && URLSegment != 'coaches-and-managers' %><i class="fa fa-caret-down"></i><% end_if %></a>
<% if $Children && URLSegment != 'coaches-and-managers' %>
<div class="collapse list-group-submenu" id="dropdown$Pos">
<% loop $Children %>
<a class="$LinkingMode list-group-item list-group-item-success" href="<% if $Children %>#dropdown$Pos<% else %>$Link<% end_if %>" <% if $Children %>data-toggle="collapse"<% end_if %> data-parent="#dropdown$Pos">$Title <% if $Children %><i class="fa fa-caret-down"></i><% end_if %></a>
<% if $Children %>
<div class="collapse list-group-submenu" id="dropdown$Pos">
<% loop $Children %>
<a class="$LinkingMode list-group-item list-group-item-success" href="<% if $Children %>#dropdown$Pos<% else %>$Link<% end_if %>" <% if $Children %>data-toggle="collapse"<% end_if %> data-parent="#dropdown$Pos">$Title <% if $Children %><i class="fa fa-caret-down"></i><% end_if %></a>
<% if $Children %>
<div class="collapse list-group-submenu" id="dropdown$Pos">
<% loop $Children %>
<a class="$LinkingMode list-group-item list-group-item-success" data-parent="#dropdown$Pos" href="$Link">$Title</a>
<% end_loop %>
</div>
<% end_if %>
<% end_loop %>
</div>
<% end_if %>
<% end_loop %>
</div>
<% end_if %>
<% end_loop %>
是這個功能可能與$ POS機，我可以看到，如果我沒有這麼多孩子的網頁，將工作..我是否需要使用js來讓這個工作？任何幫助解決方案，將不勝感激。 Drawrdesign的建議後

謝謝Drawrdesign，我可以看到如何工作，但我仍然遇到類似的問題，我會發布正在創建的代碼，以便您可以看到問題，我上一個賽季 - 繪製下拉列表具有相同的值作爲我的繪製下拉菜單：＃dropdown1-7 – OJJ
你可以隨時使用URLSegment，因爲它是唯一的我想。 例如：href =「dropdown - {$ URLSegment}」 此外，你應該做一個遞歸包含來處理這個，因爲嵌套循環通常是相同的功能。 –
感謝Ryan，我可以使用下拉菜單獲得它 - {$ URLSegment} – OJJ
