skip a line/item in asp:repeater - asp.net

Question

Is there a possible way to skip an item in asp:repeater? I have <ul> and <li>s where I need the ul to be repeated only once. Since it has id and ids must be unique.
Here I need to skip repeating the <ul id="lightgallery"> then continue repeating the <li> tags.
<asp:Repeater ID="rptBlogs" runat="server">
<ItemTemplate>
<div class="blog-post">
<div style="display:none;" id="video<%# Eval("ID") %>">
<video class="lg-video-object lg-html5" controls preload="none">
<source src="<%# !Eval("ArticleTypeValue").ParseString()%>" type="video/mp4">
Your browser does not support HTML5 video.
</video>
</div>
<div class="post-left-img">
<ul id="lightgallery"> //this needs to be skipped
<li class="video" style="position: relative;" data-poster="/<%# Eval("ThumbImage").ParseString() %>" data-sub-html="<%# Eval("Description") %>" data-html="#video<%# Eval("ID") %>" >
<a href="javascript:void(0)">
<img class="img-responsive" src="/<%# Eval("ThumbImage").ParseString() %>" />
<div class="demo-gallery-poster">
<img src="/assets/images/play-button.png">
</div>
</a>
</li>
</ul>
</div>
</ItemTemplate>
</asp:Repeater>
I know the common sense fact where the structure should be:
<ul>
<asp:repeater>
...
</asp:repeter>
</ul>
But that can't be done because of the HTML structure.
Solved but still open to better ideas. See below for my solution.

Answer 1

I used:
<ul id="lightgallery<%# Eval("ID") %>">
Instead of:
<ul id="lightgallery">
Then used jquery starts with selector:
$('[id^=lightgallery]')

Answer 2

I think a repeater in your repeater might allow you to get what you are looking for you just may have to tweak the data that you are binding.

If that doesn't work then you can add an OnDataItemBound (similar to what is shown in the link) to find/remove your control on the server side.
