Need help DRYing this code

I am new to this and need some help DRYing this view code:

<div style="float: left;">
<h3>drop task name</h3>
<ul>Projects
<% for project in @projects %>
    <% project_id = "project_#{project.id}" %>
    <li id="<%= project_id %>" class="project" style="background-color:
#CCC; margin: 0 20px 2px 0;">
        <%=h project.name %>
    </li>

    <% #TODO need to DRY up the drop_receiving_element, perhaps with a
helper%>

    <%= drop_receiving_element(
        project_id, # The id of the receiving
element
        :accept => "task_name", # The CSS class of the
dropped element
        #The action to call (update the database and then update the
project name field for that task via RJS)
        :url => { :controller => :tasks, :action => :update,
'task[project_id]'=> project.id.to_s }
        #TODO there is probably a better way to refer to the task's
project_id so that we can avoid the extra line in the update action of
the task controller
    ); %>
<% end %>
</ul>

<ul>Contexts
<% for context in @contexts %>
    <% context_id = "context_#{context.id}" %>
    <li id="<%= context_id %>" class="context" style="background-color:
#CCC; margin: 0 20px 2px 0;">
        <%=h context.name %>
    </li>
    <%= drop_receiving_element(
        context_id, # The id of the receiving
element
        :accept => "task_name", # The CSS class of the
dropped elememt
        #The action to call (update the database and then update the
project name field for that task via RJS)
        :url => { :controller => :tasks, :action => :update,
'task[context_id]'=> context.id.to_s }
        #TODO there is probably a better way to refer to the task's
context_id so that we can avoid the extra line in the update action of
the task controller
    ); %>
<% end %>
</ul>
</div>

What is the best way to do this?

Thanks,
Bill

1. You could create a partial with code between for and end, not
including them. Then u can render that partial using render :partial
=> 'something', :collection => @projects.
2. dom_id(project) is same as "project_#{project.id}"
3. Try content_tag_for(:li, project, ...) instead of <li id="<%=
project_id %>"...

You can read more about all of these methods in rails documentation
page.
