README

A simple Kirby CMS plugin that extends the pages field to apply filters to subpages in the page picker dialog.

What it does

This plugin adds a pagesfilter field type that works like the standard pages field, but applies your filter rules to all subpages shown in the picker dialog. It uses a filter parameter instead of query and shows subpages with the filter applied recursively.

Motivation

When building navigation menus, you often need to exclude certain pages (like panel structure pages or non-public pages) from the entire site hierarchy. The standard pages field only filters top-level pages, not subpages. This plugin applies filters at every level for cleaner page selection.

Installation

Via Composer

composer require basics09/kirby-pagesfilter-field

Requirements

• PHP 8.2 or higher
• Kirby CMS 4.3.1+ or 5.0+

Usage

Use the pagesfilter field type in your blueprints:

fields:
  navigation:
    type: pagesfilter
    filter: "filterBy('intendedTemplate', 'article')"
    parent: site
    label: Navigation

Filter Examples

The filter parameter uses Kirby's query language:

# Only published pages
filter: "filterBy('status', 'listed')"

# Pages with specific template
filter: "filterBy('intendedTemplate', 'article')"

# Exclude certain templates
filter: "filterBy('intendedTemplate', 'not in', ['error', 'please-donot-list-me'])"

# Custom field filtering
filter: "filterBy('featured', true)"

Field Options

All other options from Kirby's pages field are supported.

Differences from Core Pages Field

• Uses filter instead of query parameter
• Applies the filter to all subpage levels, not just immediate children
• Always shows subpages (use core pages field if you don't need this)

How It Works

The plugin extends Kirby's PagePicker to apply your filter query to each parent's children property at all page levels, and shows which pages have filtered children available.
