Refine Filters add-on module configuration settings

Here are a few notes on the Refine Filters module configuration settings:

General section

• Enable dynamic filtering (this may slow down your server): Enable/disable dynamic filtering. With dynamic filtering enabled, filters will be dynamically adjusted to your customers' needs based on the selections of filter attributes your customers make: as soon as a customer selects a certain filter attribute, the attributes that would render zero search results if combined with the selected one will appear grayed out.
  The screenshot below shows how the options 21.5-inch, None and 27-inch in the Display section of the filter appear grayed out after we have selected the Notebook option in the Type section (which is explained as being due to the fact that we do not have notebooks with 21.5- and 27-inch displays - nor notebooks without a display - in our demo store):
  
• Max number of categories in search results (0 - unlimited): Specify the maximum number of category names that can be displayed in the Filter box on search results and manufacturer pages. If a greater number of categories is found, a link to the full list of found categories will be provided.
  For example, if a customer's search has returned eight categories, whereas the 'Max number of categories in search results (0 - unlimited)' option is set to "5", the Filter box will look as follows:
  
• New filters are enabled by default: All newly generated filters are enabled for all categories.
• New filters are expanded by default: All newly generated filters are expanded for all categories.

Data Sources section

This section allows you to enable/disable the data sources on which filters are generated. For example, you may disable all but extra fields so your filters are generated based on extra fields only (Other data sources, such as product options and Feature Comparison classes, will not be used). There are also options for special filters like "Free shipping". You can hide this filter by deselecting the respective check box.

Note that this section controls filters globally for all categories. If you need to show a filter for a certain category, but hide it for other categories, you should adjust its availability for each category specifically via the Refine Filters page (see the section Managing Refine Filters below).

Appearance section

The first three settings in this section allow you to choose the types of pages on which you would like refine filters to be displayed in your store (category pages, search results pages or manufacturer pages). It is possible to choose one or more of the following options:

• Display filters on category page
• Display filters on search results
• Display filters on manufacturers page

• Show filters classes info at product details: This option displays defined filter classes on the product details page in the Customer front-end.
• Show dynamic range for sliders: This option applies only when dynamic filtering is enabled. By default, there is a blue bar on the numeric sliders which shows the actual numeric range for the filtered products. By turning this option off you can hide such blue bar and thus simplify the sliders a bit.
• Disable checkboxes for unavailable attributes in dynamic filtering: This option applies only when dynamic filtering is enabled. Filter attributes which are not available for filtered products will be gray-out, but the corresponding check boxes will not be disabled (thus allowing to result in "0 products found" if selected). If you want to disable checkboxes for unavailable attributes, turn this option on.

Managing Refine Filters

Filters can be configured at the ‘Refine Filters’ page in the admin back-end. This page can be accessed by clicking the Refine Filters link in the Catalog menu.

Once you open this page you will see the category selector:

All refine filters are tied to categories. Even though filters are displayed at the search results and at a manufacturer products pages, customer will always see filters for either the most popular category (for current search criteria) or will have to choose a category to see filters.

To manage a category filters, select the category in the dropdown:

By default it’s prefilled with automatically created filters, you can enable/disable it and adjust appearance and other settings for each filter in the category. By clicking Including subcategories checkbox you may spread the filters to all subcategories of the chosen category.

The Filters table provides the following information about each filter:

• Source: Filter source. By default all filters are enabled, but you can globally turn some filters off on the "Refine filters module settings page -> Data sources" section
• Service name: Service name of the filter. This is a unique identifier of a particular data source (e.g. service name of an extra field, class name of a product option &etc.)
• Title: Display name of the filter. This value is displayed to customers as the title of the filter.
• Enabled: Whether he filter is enabled or disabled.
• Filter view: Visual representation of the filter for customers (Multiple selector, Yes-No selector or Numeric range (slider)).
• Unit: Measurement unit for the numeric value (like "cm", "in", "gr", etc). Applicable for "Numeric range" filters only.
• Expanded: Whether the filter will be expanded on first page load. If the "Expanded" property is turned off for the filter, on first page load the filter attributes will not be shown to customers, so the customers will need to expand the filter first. This may help you save some screen space.
• Max attrs: The maximum number of attributes that will be displayed before the "More..." link. Applicable for "Multiple selector" filters only.
  The snapshot below demonstrates the look of the Color filter with the maximum number of attributes defined as "4":
  
• Columns: The number of columns to display attributes in. If you have long attribute names, you’ll probably want to set it to 1-column. But if you have a lot of short-named attributes, you should better choose 2 columns. Applicable for “Multiple selector” filters only. If "Auto" is chosen, it shows one column if there are less than Max attrs x 2 attributes, and two columns - if greater.
• Pos: Position of the filter in the filters list in the Customer area.
