Checkboxes Filter Overview

Checkboxes Filter Overview

This overview is about how to create a new Checkbox filter and apply it to different publication types using the JetSmartFilters plugin.

Checkboxes Filter is a feature that lets users select several options to filter the content on a page; it can be used on any Block Editor/Elementor/Bricks edited pages.

The filter can be built by proceeding to the WordPress Dashboard > Smart Filters > Add New page.

Filter Settings

The starting point is completing the following fields:

checkboxes list filter type selected
  • Filter Name — a name that will identify a current filter;
  • Filter Type — a list of options that contains different kinds of filters. Now, the “Checkboxes list” option should be selected.

Data source

The next field appearing after the Filter Type selection is Data Source. The option picked in this selector defines the settings available next.

The Data Source defines where the data to filter the content will be pulled. Among the options are: “Taxonomies,” “Manual Input,” “Posts,” and “Custom Fields.”

Things to know

If the JetEngine plugin is installed and activated, the “JetEngine Custom Content Types,” “JetEngine Glossary,” “JetEngine Query Builder,” and “JetEngine Query Builder SwitcherData Source options also become available. Some of them appear only when the corresponding modules are activated.


This option will take the data from the selected taxonomy. For instance, it can be categories, tags, or product taxonomies.

taxonomies data source
  • Taxonomy — the taxonomy that will be used for filtering;
  • Relational Operator — a selector that allows picking the relational operator. The “Union” operator will display results corresponding to at least one of the selected checkboxes. For example, if “House” and “Villa” options are selected, items belonging to either category will appear. For the “Intersection” option, the result is vice versa. Only items that belong to both “House” and “Villa” options will be displayed;
  • Show empty terms — if enabled, the empty terms that have no items assigned to them will also be shown on the list;
  • Show only childs of current term — on the parent category archive, only its child categories will be shown. On all other pages, all categories will be displayed;
  • Group terms by parents — this option should be switched on to save the hierarchical structure where child terms are listed under the parent ones. If enabled, the Collapsible toggle becomes available and, if activated, makes the child objects appear after clicking on the parent term;
  • Is Checkbox Meta Field — this option should be enabled to filter items by the Checkbox meta field saved as an array, Select meta field saved as multiple select, Posts meta field saved as multiple, or Checkbox meta field of ACF. This option is mainly used for filters with the Custom Fields source;
Things to know

The Is Checkbox Meta Field option should be disabled if the “Taxonomies” Data Source is selected. This option should only be enabled when filtering by custom meta fields mentioned above.

  • Exclude/Include — a feature that can be used to include or exclude some of the terms so they will be or will not be shown in the options list;
Things to know

The “None” option in the Exclude/Include setting should be chosen if no terms should be included or excluded.

  • Use Custom Query Variable — this setting is unrequired for the “Taxonomies” Data Source. This setting can be enabled to filter items related by the Relations feature of the JetEngine plugin. For example, if the given taxonomy is the child object or the parent object in a relation, it is possible to use this taxonomy to filter the related objects. Follow another tutorial to find more information on how to filter related items.

Manual input

This source allows adding the Checkbox Filter options manually. Among unique settings are:

manual input data source
  • Options List — an area where the manual options can be added and edited by clicking the “Add New” button;
  • Query Variable —  an obligatory field where the query variable key should be put. When filtering by a meta field, one should copy and paste the Name/ID of the meta field into the Query Variable field. Multiple field keys should be separated with commas.


Posts can also become a source for the filter. This source includes the following unique setting field:

posts data source
  • Post Type — a post type that will be used as the source for filtering.

Custom Fields

The “Custom Fields” source allows customizing the following set of fields:

custom fields data source
  • Custom Field Key — a custom field key that will be used as the source for filtering;
  • Get Choices From Field Data — the setting that makes the filter take the filter options from the options of the meta field.

JetEngine Glossary

The option is available if the JetEngine plugin is installed and activated. To make the Glossary a filter source, one should fill in the following settings:

jetengine glossary data source
  • Select glossary — a glossary that will serve as the data source.

JetEngine Query Builder

The option is available if the JetEngine plugin is installed and activated. The source, in this case, is the Query from JetEngine; it includes the following settings:

jetengine query builder data source
  • Select Query — a query that will serve as the data source;
  • Property to Get Value from — a field that indicates where the value for the options will be taken. By default, it is set to “ID”;
  • Property to get Label from — a field that indicates where the label for the options will be taken. By default, it is set to “post_title.”

JetEngine Query Builder Switcher

The option is available if the JetEngine plugin is installed and activated. This source allows switching between content queries.

Use Default Filter Value

Use Default Filter Value is a toggle that activates the Default Filter Value field. Values there can be separated by commas; they will be applied to the provider once via an Ajax request when the filter is added to the page.

Filter Labels

Filter labels can be adjusted in the corresponding part of the settings:

filter labels section
  • Filter Label — a label that can be displayed next to the filter;
  • Active Filter Label — a label shown if the filter is active.

The filter can be saved by pushing the “Update” button.

Checkboxes Filter Widget in Elementor

The Checkboxes Filter widget is available in the Elementor Page Builder. The widget contains the following settings:


content settings in elementor
  • Select filter — a bar where the name of the filter should be put so it appears on the page;
  • This filter for — a provider list to pick the widget to which the filter will be attached;
  • Apply type — a field to choose a way the filter will work. Presented options: “AJAX,” “Page Reload,” and “Mixed.” “AJAX” displays results without reloading the page, “Page Reload” reloads a page, and “Mixed” doesn’t reload a page but transforms the page URL.

With the “Page Reload”, the “Apply” button should be used.

  • Apply on — a field to pick when the filter is applied: once the value changes or by clicking the “Apply” button;
  • Show apply button — a switcher to be activated if the “Click on apply button” option is selected in the previous Apply on selector;
  • Show filter label — a toggle that shows a filter label above the filter;
  • Query ID — a field that can be used if there are several widgets of the same type on the same page, and one is supposed to be used as a provider. For instance, if there are two Listing Grids on the page and only one should be filtered, the Listing Grid settings (Advanced tab) should be opened, and its unique name should be set in the CSS ID field and then put here, in the Query ID field of the filter;
  • Additional Providers Enabled — a toggle to be enabled if several widgets should be filtered.

If the Additional Providers Enabled toggle is switched on, more settings are displayed:

additional providers enabled feature in elementor
  • Additional Provider — a drop-down list to select an extra provider;
  • Additional Query ID — an ID to be set if several identical widgets are on the page. Works as the Query ID field described earlier.

Additional settings

    • More Text — a text on the “More” button;
    • Less Text — a text on the “Less” button.

N selected
n selected feature
  • Number of Named Items — a field where the number of shown labels can be specified. For instance, if “3” is set, after three labels, there will be a text “and 1/2/3… others” shown;
  • Generic text — a text displayed after labels. Mind that a {number} macro should be used in the text to generate value afterward.
