<p>Hi,</p>
<p>Yes indeed, there is a large overlap between the two and it would
be nice to unite them in the future.</p>
<p>Most of the recent work has gone into the relation reference
widget, but unfortunately there are still some things that will
need to be implemented on the relation reference widget before the
value relation widget can be declared obsolete (and I did not yet
make a comprehensive list).</p>
<p>Nyall, what would be required to bring this functionality also
(or only) into the relation reference widget? I guess the work
that has gone into the preparation for this crowdfunding will make
it a lot easier also to implement this in the relation reference
widget?</p>
<p>Best regards</p>

<p>Hi Nyall,</p>
<p>Interesting campaign and definitely some needed feature that
will help further improve forms in QGIS.</p>
<p>However, I wonder why you chose the "value relation widget" and
not the "relation reference widget". Both widget types have a
larger overlap in functionality and I did hope that we could get
rid of one of the two widgets in the future. Because from a user
perspective it is confusing that different widget types exist
that do similar things.</p>
<p>I had the impression that the team around Denis/Matthias is
pushing the "relation reference widget" and had the plan to
implement in the relation reference widget everything the "value
relation widget" does.</p>
<p>Matthias - please correct me if I am wrong.</p>
<p>Nyall/Matthias/Denis: What are your thoughts on the redundant
functionality in both widgets? Could we merge the two into one
widget?</p>
<p>Greetings,<br>
Andreas</p>

<br>
North Road are proud to launch our latest QGIS crowd-funding
campaign:<br>
Drill-down (cascading) forms! This campaign covers extending
the<br>
functionality present in QGIS "Value Relation Widgets",
allowing the<br>
implementation of complex, dynamic filters within QGIS
attribute<br>
forms. The functionality can be used to implement "drill-down"
forms<br>
within QGIS, where the values available in one field depend on
the<br>
values of other fields.<br>
<br>
Full details are available at the campaign page:<br>

<br>
We need your help to make this feature a reality! We need
backers, but<br>
just as importantly, we need people to spread the word about
this<br>
campaign so that all interested users and organisations hear
about it.<br>
Here are some ideas:<br>
<br>
- spread the campaign page via your social media accounts:
Twitter,<br>
Linked in, etc<br>
- forward a link to the campaign to any relevant professional
networks<br>
you're part of<br>
- publicise the campaign via your local QGIS user group<br>
- have a chat to your manager... if this feature will make
your work<br>
easier, and you've saved money by implementing QGIS within
your<br>
organisation, consider contributing and let us make your job
easier!<br>
<br>
Stay tuned for more updates and posts exploring this feature
as the<br>
campaign progresses...<br>
<br>
Nyall<br>
