Retrieve Structure Top Level Pages

Question

I find myself struggling with some of Structure's documentation and cannot find an answer via Google either, here's the skinny:

Currently have 2 top level "pages" (2 more but are hidden because I dont need them in the nav list). Each of these have children pages and everything is dandy and working.

Top Level Page1 - overview template / Channel1
    + Child Page -- Display template / Channel2
    + Child Page -- Display template / Channel2

Top Level Page2 - overview template / Channel1
    + Child Page -- Display template / Channel2
    + Child Page -- Display template / Channel2

I now need to take those 2 "top" level pages and insert them into a select dropdown for some JS sorting on a page that isn't managed by Structure, like this:

Project Overview -- show all entries template - Channel2
    {exp:channel:entries}
    // Works well, spits out Channel2 data no prob
    //This is what I need
    <option value="{structure:parent:id}">structure:parent:name</option>

Have tried:

{exp:structure:nav start_from="/" max_depth="1"}
  <option value="{page_uri}">{title}</option>
{/exp:structure:nav}
//This code works well in nav

This yields nothing (blank code), the docs allude that using :nav sets an li which I dont want & likely causing nothing to output.

I expect because Structure isn't managing the "projects" page, finding a parent or anything to do with normal exp:channel:entries tag is the roadblock.

Thought about adding Top Level pages as children of a new 'parent' but then I'd have another list item in the main nav which we dont want.

Totally stumped :(

Answer 1

You'll need to use the Structure Entries add-on for this. Here's the basic idea (full docs can be found at the devot-ee page):

<select id="Menu" name="menu">
  {exp:structure_entries  depth="1"}
    <option value="{page_uri}" {if {current_page}}selected{/if}>{title}</option>
  {/exp:structure_entries}
</select>

Answer 2

For those interested and for my future self, I basically need to add id's to 2 select dropdpowns (1 for category and for one to identity which parent it belongs to) + also replicate on 2 data values for each entry.

This is all outside the Structure framework, I'm querying only the children entries with a simple exp:channel:entries but no native way to query who its parent is.

/* Simple enough to add top value entry_ids
<select name="disciplines" data-label="Filter by Disciplines">
  <option selected="selected" value="all">All Disciplines</option>
  {exp:structure_entries depth="1" hide_from_nav="yes"}
    <option value="{entry_id}">{title}</option>
  {/exp:structure_entries}
</select>

/* Bit of a no brainer getting the categories
<select name="market" data-label="Filter by Market">
<option selected="selected" value="all">All Markets</option>
  {exp:gwcode_categories style="linear" channel="project_detail" show_empty="no"}
    <option value="{cat_url_title}">{cat_name}</option>
  {/exp:gwcode_categories}
</select>

Now the fun part, mighty Croxton Stash + Structure Entries FTW

/* Simple list of relationships !!
{exp:stash:set_list name="associated" parse_tags="yes" trim="yes"}
    {exp:structure_entries  hide_from_nav="yes" parse="inward"}
        {stash:parentid}{parent_id}{/stash:parentid}
        {stash:entryid}{entry_id}{/stash:entryid}
    {/exp:structure_entries}
{/exp:stash:set_list}

THE MAGIC = match + against !!

{exp:channel:entries channel="project_detail"}
<article data-disciplines="{exp:stash:get_list name='associated' match='#{entry_id}#' against='entryid'}{parentid},{/exp:stash:get_list}"
data-market="{exp:gwcode_categories entry_id='{entry_id}' style='linear' backspace='1'}{cat_url_title},{/exp:gwcode_categories}">
... remainder of layout for product ...
{/exp:channel:entries}
