<h2 id="why">Menus: Why we need a change now</h2>
<h4>Phones</h4>
<p>The <a href="#whatold">current system</a> makes it very difficult to design menus that work on phone screens.
Phones are now the primary access method and the current menus actively get in the way rather than provide useful function.
They have to be fixed.
<h4>Higher level, lower-level menus and context</h4>
<p>
Secondly, we observe that many users never look at the menus. From using other websites they are used to seeing the important links in the text of the page
they are reading. This is particularly true for pages documenting a
sequence of operations such as the <em>sketch-wallet-survex-drawings</em> sequence. This is also how well-designed websites work these days: lots of white
space and any necessary navigation clearly <em>in</em> the page.
<p>
An excellent guide is the
<a href="https://www.gov.uk/guidance/government-design-principles">gov.uk design principles</a>
web pages which practice what they preach. They have a "Related Content" menu to one side,
breadcrumbs showing the page context, more remote organisation menu along the top of the page and two
or three fine-print menus at the bottom of the page for potentially relevant standard stuff.
<p>Users need "situational awareness" in that they like to know "where they are" in the system. This is not the same thing as a menu list of links to "places you might like to go to". But these two different things are both called "navigation". The gov.uk design guide separates these two things and we should too.
<p>Another reason that users don't use the menus is inconsistency. This is partly because the menus don't
match the <a href="#user">mental model they have</a> of how the system is put together and partly
because <a href="#maint">maintenance difficulties</a> have created
an inconsistent system.
<p>The menu system we created a decade ago was leading-edge in its time but user expectations have moved in a different direction.
<br /><em>[This document originally written 19 February 2020, updated 2 April 2020]</em>
<h2 id="maint">Menus: Maintenance constraints</h2>
<p>
Experience over the past 10 years shows that having menus embedded in each page (see <a href="#whatold">What we have now</a>) is
unworkable long-term.
<p>
People create new pages typically by editing a copy of the last page they edited.
This might have been from an entirely different part of the system.
So we end up with "survey documentation" menus on a page which is in the middle of a "basecamp operations" set of pages.
We cannot control the behaviour
of page editors and we are very grateful to them so we don't want to add to their workload or make
things messy or difficult.
<p>See the Proposals sections below for how we might make this easier.
<p>A maintenance constraint is that we should have <em>a small number</em> of different menus.
<h2 id="user">Menus: User mental model constraints</h2>
<p>This is where we have a real problem. Even nerds editing the system have different ideas
of how they visualise it.
<p>Most users have no picture at all of the distinctions between "the handbook",
the "local area", the "cave survey data", the "software maintainers guide" parts.
Some people only interact with only one part of the system and are entirely
unaware of the rest of the system.
<p>Some pages which are definitely in the mental "how to do expo" category are not just hand-edited handbook webpages,
for example some prospecting guides are generated from cave data.
<p>Some pages have to be updated very differently fom others. The "cave descriptions" are particularly difficult for
someone used only to interacting with an HTML editor or a wiki. But for most users this distinction is invisible.
<p>The current set of menus suffer greatly from "bleed through" in that they mimic the hidden internal structure
of the system rather
than (as they should) the user mental model of how users want to interact with it.
<p>A user mental model constraint is that menus should be predictable,
so we should have <em>a small number</em> of different menus.
<h2 id="prop1">Menus: Proposal #1 - One Single Menu</h2>
<h4>Architecture</h4>
<ul>
<li>One standard menu used on every single page.
<li>Generated dynamically by troggle.
</ul>
<p>This will need quite a bit of thought and discussion as to what should be in the menu.
We should test this with a variety of real users, or roll it out and be very responsive to change requests.
<h4>Implementation</h4>
<ul>
<li>Entirely done in CSS as currently, and
<li>inserted by troggle either just before the final
<span style="font-family:monospace; font-size: medium; background-color: lightgray">&lt;/body&gt;</span>
tag or at the beginning immediately after the initial
<span style="font-family:monospace; font-size: medium; background-color: lightgray">&lt;body&gt;</span>
tag.
<li>A bit of tricky awk required to remove all the tags with
<span style="font-family:monospace; font-size: medium; background-color: lightgray">id="links"</span>
attributes. But just an evening's work.
</ul>
<h4>Advantages</h4>
<ul>
<li>Excellent predictability for users
<li>Simple to implement: minimal changes to the existing system.
<li>No effort whatsoever on page editors and content typers
<li>No conflicting menus from different sources appearing on the same page
<li>"Edit this page" can appear or not depending on user authorisation or (for generated pages) entirely absent.
<li>Universal single update: change once changes menus for whole system
</ul>
<h4>Disadvantages</h4>
<ul>
<li>No menus offline
<li>No fine-grained menu when in the middle of a complex part of the system
</ul>
<h2 id="prop2">Menus: Proposal #2 - Different menus per "sector"</h2>
<h4>Architecture</h4>
<ul>
<li>Every page in the system is identified (how?) as being "in" one of half a dozen "sectors", e.g.
handbook, handbook-emergency, final cave data, survey procedures, software documentation, software maintenance etc.
<li>troggle inserts the menu dynamically depending on the page "sector" id.
</ul>
<h4>Implementation</h4>
<ul>
<li>All programmed within troggle
<li>page editors will need to insert an identifying tag, OR
<li>we restructure the folders completely and have troggle use the folder structure to decide which "sector" is which
</ul>
<h4>Advantages</h4>
<ul>
<li>Fine-grained menus potentially more useful (if users use them)
</ul>
<h4>Disadvantages</h4>
<ul>
<li>Will need visible flagging to users which "sector" they are in,
otherwise the different menus appearing may disorient them
<li>If implemented by folder restructuring: all links in to the website, e.g. in historic emails, all the Slack posts, all the UKcaving blog posts etc. etc.
will <em>break</em> unless we create a large redirection list in the apache configuration files.
<li>If implemented by manual tag insertion in every page: page editors will get it wrong sometimes (but each fix is easy)
</ul>
<h2 id="prop2">Menus: Proposal #3</h2>
<p>Do Proposal #1 now.
<p>Do Proposal #2 later - if it turns out to be needed. (Probably by tag method not folder method.)
<p>&nbsp;
<p>
<h2 id="whatold">Appendix - Menus: What we have now</h2>
<p>Today (February 2020) we have two separate menu systems which look identical:
<ol type=A >
<li>Menu links as HTML text on individual webposite pages, either hand-edited (handbook) or
generated as HTML pages by occasional offline scripts (such as the deep/long caves page) , or
<li>Auto-created menus constructed <em>on the fly</em> by troggle at the moment that a page is served by the webserver.
This happens for every single page of every type.
</ol>
<h4>Type A - static menus</h4>
<p>The first type, the "static"menus, are created by HTML like this, with a
<span style="font-family:monospace; font-size: medium; background-color: lightgray">id="links"</span>
tag attribute which creates the styling:
<pre><code>&lt;!-- LINKS --&gt;
&lt;div id="menu"&gt;
&lt;ul id="links"&gt;
&lt;a href="index.htm"&gt;Handbook&lt;/a&gt;
&lt;a href="survey/index.htm"&gt;Surveying&lt;/a&gt;
&lt;a href="look4.htm"&gt;Prospecting&lt;/a&gt;
&lt;a href="rescue.htm"&gt;Rescue&lt;/a&gt;
&lt;/ul&gt;
&lt;/div&gt;</code></pre>
<p>This text is conventionally at the bottom of each HTML file. (It does not have to be at the bottom,
the CSS handles where on the page this appears visually, so this HTML fragment could be anywhere
in the HTML file.)
<p>The visual rendering of the menus is controlled by lines 120-215 in <a href="../../css/main2.css">main2.css</a> -
thanks to a succession of clever and inventive people.
<p><p>
Here is an example of a more extensive menu. Note that changes to CSS over the years now mean that this
overflows the menu box because the annotations are too long for the box width:
<pre><code>&lt;!-- LINKS --&gt;
&lt;div id="menu"&gt;
&lt;ul id="links"&gt;
&lt;li&gt;&lt;a href="index.htm"&gt;Expedition Handbook&lt;/a&gt; - Intro
&lt;ul&gt;
&lt;li&gt;&lt;a href="survey/index.htm"&gt;Surveying guide&lt;/a&gt; - Overview&lt;/li&gt;
&lt;li&gt;&lt;a href="look4.htm"&gt;Prospecting guide&lt;/a&gt; &ndash; Overview
&lt;li&gt;&lt;a href="rescue.htm"&gt;Rescue guide&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;&lt;a href="rig/rigit.html"&gt;Rigging guide&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;&lt;a href="photo.htm"&gt;Photography guide&lt;/a&gt;&lt;/li&gt;
&lt;/ul&gt;&lt;/li&gt;
&lt;li&gt;&lt;a href="../infodx.htm"&gt;Index to info/topics pages&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;&lt;a href="../indxal.htm"&gt;Full Index to area 1623&lt;/a&gt;
&lt;ul&gt;
&lt;li&gt;&lt;a href="../areas.htm"&gt;Area/subarea descriptions&lt;/a&gt;&lt;/li&gt;
&lt;/ul&gt;&lt;/li&gt;
&lt;li&gt;&lt;a href="../index.htm"&gt;Back to Expedition Intro page&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;&lt;a href="../../index.htm"&gt;Back to CUCC Home page&lt;/a&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;</code></pre>
<p>There are <span style="text-decoration: line-through wavy red;">a few</span> 546 pages (out of hand-edited 1,022 HTML pages) where the enclosing
<span style="font-family:monospace; font-size: medium; background-color: lightgray">DIV</span>
tag is omitted. In these cases troggle inserts its own menu <em>in addition to</em> the static menu. The result is a confusion of two menus. These pages are in currently being identified and corrected.
<h4>Type B - dynamic (troggle) menus</h4>
<p>This menu is a fragment of HTML inserted by troggle on the fly as the page is served to the user.
It is inserted immediately before the closing
<span style="font-family:monospace; font-size: medium; background-color: lightgray">&lt;/body&gt;</span>
tag.
It has one thing which cannot be done by static menus: it has the <font color=red>"Edit this page"</font> link
at the bottom which is the troggle (Django) wiki-style editing system:
<pre><code>&lt;ul id="links"&gt;
&lt;li&gt;&lt;a href="/index.htm"&gt;Home&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;&lt;a href="/infodx.htm"&gt;Main Index&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;&lt;a href="/troggle"&gt;Troggle&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;&lt;a href="/areas.htm"&gt;Areas&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;&lt;a href="/indxal.htm"&gt;Caves&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;&lt;a href="/handbook/index.htm"&gt;Handbook&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;&lt;a href="/pubs.htm"&gt;Reports&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;&lt;a href="/handbook/<font color=red>menudesign.html_edit</font>" <font color=red>class="editlink"</font>&gt;&lt;strong&gt;<font color=red>Edit this page</font>&lt;/strong&gt;&lt;/a&gt;&lt;/li&gt;
&lt;/ul&gt;
</code></pre>
<p>Note that the last line is different for every page and autogenerated.
<p>
The dynamic menu is rendered by exactly the same CSS
<span style="font-family:monospace; font-size: medium; background-color: lightgray">id="links"</span>
as the static menu.
<p>Note that there is no
<span style="font-family:monospace; font-size: medium; background-color: lightgray">&lt;div id="menu"&gt;</span> enclosing
<span style="font-family:monospace; font-size: medium; background-color: lightgray">div</span>
tag. The
<span style="font-family:monospace; font-size: medium; background-color: lightgray">div</span>
tag is only there to tell troggle that there is a static menu and so it shouldn't provide one.
<p>For the past 3 years the static menus have been mostly removed from edited pages as the dynamic menu did the job, and
often both would appear which was ugly. This page has both menus:
<a href="http://expo.survex.com/dplong.htm">Lengths and depths of caves in the 1623 area</a>.
<h2 id="offline">Appendix - Menus: Offline constraint</h2>
<p>It is handy if a completely offline copy of the website
- just the HTML files and CSS - still has a useable (if cut-down) menu system. (This used to be vital when the potato hut
server troggle stopped but the server could still provide HTML files. Not any more.)
But this is increasingly unnecessary for most of the people using it.
<p>The most likely use-case would be someone on the plateau (or possibly underground)
needing to read the handbook pages on rescue or first-aid procedures using a locally-stored copy
of the entire handbook. Most people won't have done in this in advance of the need or wouldn't know how
to do it anyway. If they can do this, they are not likely to be relying on the menu system to find what they want.
<p>Can anyone think of other cases where menus for offline use might be useful?
<h4>Files for download as an alternative</h4>
<p>We could meet this very specific requirement without messing with our menus. We could have a complete set of
downloadable documents (e.g. PDF) of prospecting guides and safety procedures - including topcamp and basecamp phone numbers -
which we encourage all expoers to download to their phone before they leave base-camp.
We already have a number of these but some are in .odt format which is not phone-friendly. But that is another job to fix.
