Collapsible Groups for Exposed Filters

The exposed forms are pluggable, so it would be able to write a plugin which makes this possible.
This plugin can live in contrib somewhere else, so views keeps clean.

dagmar1 wrote already some stuff with exposed form plugin.

You can wrap all the views-exposed-form.tpl.php template into a collapsible fieldset using this template: more info here: http://drupal.org/node/118343#comment-1442786

<?php if (!empty($q)): ?>
  <?php
    // This ensures that, if clean URLs are off, the 'q' is added first so that
    // it shows up first in the URL.
    print $q;
  ?>
<?php endif; ?>

<?php
drupal_add_js('misc/collapse.js');
?>

<fieldset class = "collapsible">
  <legend class="collapse">
    <a href="#">Views Filters</a>
  </legend>
  <div class="fieldset-wrapper">
    <div class="views-exposed-form">
      <div class="views-exposed-widgets clear-block">
        <?php foreach($widgets as $id => $widget): ?>
          <div class="views-exposed-widget">
            <?php if (!empty($widget->label)): ?>
              <label for="<?php print $widget->id; ?>">
                <?php print $widget->label; ?>
              </label>
            <?php endif; ?>
            <?php if (!empty($widget->operator)): ?>
              <div class="views-operator">
                <?php print $widget->operator; ?>
              </div>
            <?php endif; ?>
            <div class="views-widget">
              <?php print $widget->widget; ?>
            </div>
          </div>
        <?php endforeach; ?>
        <?php if (!empty($sort_by)): ?>
          <div class="views-exposed-widget">
            <?php print $sort_by; ?>
          </div>
          <div class="views-exposed-widget">
            <?php print $sort_order; ?>
          </div>
        <?php endif; ?>
        <?php if (!empty($items_per_page)): ?>
          <div class="views-exposed-widget">
            <?php print $items_per_page; ?>
          </div>
        <?php endif; ?>
        <?php if (!empty($offset)): ?>
          <div class="views-exposed-widget">
            <?php print $offset; ?>
          </div>
        <?php endif; ?>
        <?php if (!empty($reset_button)): ?>
          <div class="views-exposed-widget">
            <?php print $reset_button; ?>
          </div>
        <?php endif; ?>
        <div class="views-exposed-widget">
          <?php print $button ?>

Sorry, a support request does not indicate that we will create a new plugin for your use case. If we tell you how to accomplish something in a support request, it can be mark fixed. Given the number of possible plugins that are out there, you may rest assured that the vast majority of minor use cases will not have new plugins created for Views that will ship with it.

The whole reason Views is pluggable is so that when Views doesn't do something you need it to do, but it is possible with a plugin, you can write the plugin for your purposes. You can use it just on your site or release it as a module.

I can't open the page http://drupal.org/node/118343#comment-1442786
"Access denied
You are not authorized to access this page."

Should I be the member of some group or else?

Also can be put in views-view.tpl.php:

<?php if ($exposed): ?>
    <?php
      drupal_add_js('misc/collapse.js', 'core');
    ?>
    <fieldset class="collapsible collapsed">
      <legend class="collapse">
        <a href="#">Exposed filters</a>
      </legend>
      <div class="view-filters fieldset-wrapper">
        <?php print $exposed; ?>
      </div>
    </fieldset>
  <?php endif; ?>

For anyone who's interested, if you want to implement this in drupal 7 here is a working example:

<?php if (!empty($q)): ?>
  <?php
    // This ensures that, if clean URLs are off, the 'q' is added first so that
    // it shows up first in the URL.
    print $q;
  ?>
<?php endif; ?>

<?php 
drupal_add_library('system', 'drupal.collapse');
drupal_add_js('misc/collapse.js');
?> 
  <fieldset id="fieldset-id"  class = "collapsible">
  <legend> <span class="fieldset-legend"> sadfasdf</span>
     
  </legend>
  <div class="fieldset-wrapper">
  <div class="fieldset-description">Fieldset description</div>
    <div class="views-exposed-form">
      <div class="views-exposed-widgets clear-block">
        <?php foreach($widgets as $id => $widget): ?>
          <div class="views-exposed-widget">
            <?php if (!empty($widget->label)): ?>
              <label for="<?php print $widget->id; ?>">
                <?php print $widget->label; ?>
              </label>
            <?php endif; ?>
            <?php if (!empty($widget->operator)): ?>
              <div class="views-operator">
                <?php print $widget->operator; ?>
              </div>
            <?php endif; ?>
            <div class="views-widget">
              <?php print $widget->widget; ?>
            </div>
          </div>
        <?php endforeach; ?>
        <?php if (!empty($sort_by)): ?>
          <div class="views-exposed-widget">
            <?php print $sort_by; ?>
          </div>
          <div class="views-exposed-widget">
            <?php print $sort_order; ?>
          </div>
        <?php endif; ?>
        <?php if (!empty($items_per_page)): ?>
          <div class="views-exposed-widget">
            <?php print $items_per_page; ?>
          </div>
        <?php endif; ?>
        <?php if (!empty($offset)): ?>
          <div class="views-exposed-widget">
            <?php print $offset; ?>
          </div>
        <?php endif; ?>
        <?php if (!empty($reset_button)): ?>
          <div class="views-exposed-widget">
            <?php print $reset_button; ?>
          </div>
        <?php endif; ?>
        <div class="views-exposed-widget">
          <?php print $button ?>
        </div>
      </div>
    </div>
  </div>
</fieldset> 

Thanks for the D7 version, but does anybody know how to go about keeping the default classes available for each exposed filter? It's great having the fieldset, but not being able to move each filter around individually isn't exactly optimal.

So #11 worked great for me. However, does anyone know how to make the fieldset collapsed by default?

You should be able to just add "collapsed" into the fieldset class beside "collapsible."

perfect. thanks!

This almost works for me. The text in the legend doesn't do anything when clicked. Adding the class "collapsed" will collapse my exposed filters but clicking on the legend doesn't open or close it. Any ideas?

*Update* Turned off the Superfish module and it worked. Any ideas what could be causing that?

There is one problem with the suggested solution for D7: if you add the "collapsed" class, when the page reload the filter is collapsed, but when at least a filter is selected it should be better to display the exposed filters (from a usability point of view).

A solution would be to conditionally add the "collapsed" class counting the number of $_GET parameters:

<fieldset class=" collapsible <?php print (count($_GET) == 1) ? 'collapsed' : ''; ?>">

I hope it will be useful.
