Specifications

Define global custom fields that appear on every rental product — vehicle capacity, fuel type, features, year, color, and more.

1: Introduction

Specifications are global field definitions — you create a field once here, and it becomes available on every rental product's edit screen under Advanced Settings → Specifications. Each product then fills in its own value for each spec field.

Examples of typical specification fields: Seats (number), Fuel Type (select), Transmission (radio), Air Conditioning (checkbox), Color (color), Manufacturer Year (number), Brochure (file).

2: How It Works

Step	Where	What happens
1. Define fields	BRW → Specifications	Create spec field definitions (type, name, label, options, etc.)
2. Fill per product	Product Edit → Advanced Settings → Specifications	Each product gets an input for every enabled spec field; admin fills in the value
3. Display on frontend	Single product page / Card template	Enabled specs with values are shown in the product's specifications section. Fields with Show in Card also appear in listing cards.

3: Specifications List — Table Columns

Column	Description
Checkbox	Select for bulk actions. "Select all" checkbox in header/footer selects all rows.
Type	Field type (text, number, select, etc.). Also stored in a hidden field used during operations.
Name	The internal slug/key of the field. Unique, lowercase, no spaces. Used as the array key in storage.
Label	The human-readable display name shown to admins (in the product edit screen) and optionally on the frontend.
Icon font	CSS class for an icon (e.g. flaticon-users) displayed alongside the spec on the frontend.
Enable	Green checkmark (✓) = enabled; blank = disabled. Disabled specs are visually greyed out in the list.
Actions	Edit, Delete, Visibility toggle (👁 = disable / 🚫 = enable), Drag handle (⣿) for reordering.

3.1 Bulk Actions

Four buttons at the top of the page operate on selected (checked) rows.

Button	Action	Behavior
Add new	Open add popup	Opens the Add Specification popup modal. Does not require any selection.
Delete	Delete selected	Removes all checked specification definitions. Irreversible — does NOT prompt for confirmation. Product meta values for deleted specs remain in the DB but are no longer rendered.
Enable	Enable selected	Sets enable = 'on' for all checked specs. Enabled specs appear in product edit screens.
Disable	Disable selected	Sets enable = '' for all checked specs. Disabled specs are hidden from product edit screens and frontend display.

3.2 Row Actions

Edit

• Opens the Edit popup modal pre-filled with the field's current values. All fields are editable including Name (slug) — renaming a spec updates all references to the old name in the global options array.

Delete

• Deletes this single specification immediately (no confirmation prompt). Submits the form with action = delete and the field name.

Visibility Toggle

• Toggles a single spec between enabled (👁 active, 🚫 hidden) and disabled (🚫 active, 👁 hidden). Disabled rows appear greyed out. AJAX-saves without page reload.

Drag & Drop Reorder

• Grab the drag handle (⣿) to drag rows up or down. The new order is saved automatically via AJAX on drop. The display order on the frontend follows the order in this list.

4: Add / Edit Popup — All Fields

Select Type - Required

• Dropdown with 11 field types. Determines which input control is rendered in the product edit screen and what the Default field looks like. See Field Types section for full details.

  Changing the type on an existing spec (Edit) re-renders the popup form instantly. Changing from a type with Options (radio/checkbox/select) to one without hides the Options table.

Name - Required

• Internal identifier / array key. Rules: unique, lowercase only, no spaces (use underscore:

• When editing, if you change the name, the plugin renames the key in the global spec array (all product meta values previously stored under the old name become orphaned — update product meta manually if needed).

Label - Required

• Display name shown to admins in the product edit screen and, when Show label is checked, on the frontend product page next to the spec value.

Options

• Appears only for types: Radio Checkbox Select. A sortable mini-table of option values. Each row has a text input, a + button (add row below), an × button (remove row), and a drag handle to reorder options.

  At least one option is required for these types.

Icon font - Option

• A CSS class string for an icon font (e.g. flaticon-users, brwicon2-seat). Find icon class here

Default - Option

• A pre-filled default value for this spec on every product that hasn't set it manually. The input type varies by field type:

• Type	Default input
  Text Tel	Text input
  Link	URL input (type="url"), placeholder https://example.com
  Number	Number input
  Email	Email input
  Color	Color picker (type="color")
  Date	Date picker (BRW datepicker widget)
  File	"Add file" button opening WP Media Library; stores attachment ID in hidden field
  Radio Checkbox Select	Text input (free-text default; per-product selection overrides)

Class - Option

• Extra CSS class added to the spec wrapper element on the frontend. Use for custom styling or JavaScript targeting.

Field Types

11 input types are available. The type controls both how the value is entered in the product edit screen and how it is displayed on the frontend.

Type	Product Edit Input	Use Case	Options needed
Text	Single-line text input	Short labels, model names, descriptions	—
Link	URL input (type="url")	Brochure URL, manual PDF link	—
Number	Number input	Seats, doors, horsepower, year	—
Tel	Telephone input (type="tel")	Contact/support number	—
Email	Email input (type="email")	Contact email for vehicle manager	—
Radio	Radio button group	Transmission (Auto / Manual), Fuel type (one choice)	✓ Required
Checkbox	Checkbox group	Features (AC, GPS, Child seat — multiple)	✓ Required
Select	Dropdown (optionally multi-select)	Color, Body type, Category	✓ Required
Date	Date picker	Registration date, Last service date	—
Color	Color picker (type="color")	Vehicle exterior color swatch	—
File	WP Media Library picker; stores attachment ID	User manual PDF, spec sheet	—

The Select type has an extra Multiple checkbox in the popup. When checked, the select renders as a multi-select (multiple attribute) allowing admins to pick several values per product.

Add custom types with the filter ovabrw_specification_get_types. The filter receives the types array and must return it with your additions.

Status Flags: Three checkboxes at the bottom of the Add/Edit popup control display behavior.

• Enable: When checked : the spec appears in the product edit screen's Specifications panel, and is included in frontend output. When unchecked: completely hidden from both admin and frontend.

• Show label: When checked: the Label text is displayed alongside the spec value on the frontend (e.g. "Seats: 5"). When unchecked: only the value is shown (e.g. just "5" with its icon).

• Show in Card template: When checked: the spec (and its value) is also displayed on the compact Card view (product listing cards / archive cards). When unchecked: the spec appears only on the full single-product page.
