Before installing the extension, you need to install Meta Box plugin first.

  1. Go to Plugins → Add New and search for Meta Box
  2. Click Install Now button to install the plugin
  3. After installing, click Activate Plugin to activate the plugin

The extension is just a WordPress plugin, you can install it like a normal WordPress plugin.

  1. Go to Plugins, click Add new, then click Upload plugin.
  2. Choose the .zip file you downloaded and click Install now
  3. After finishing upload, click Activate to finish.


Make sure you know how to register meta boxes and define fields before continuing!

To add a tooltip to a meta field, simply add tooltip parameter for that field. You can define tooltip in one of following formats:

  • 'tooltip' => 'Tooltip content',
  • 'tooltip' => array( 'icon' => 'info', 'position' => 'top', 'content' => 'Tooltip content' )

e.g. if the tooltip is a string, the plugin will use icon info and take the string as the tooltip content. If the tooltip is an array, then it accepts the following parameters:

iconThe tooltip icon. It can be info (default), help or URL to custom icon image. Since version 0.1.1, you can use any Dashicons for the icon by specifying its name, for example dashicons-email. For full list of Dashicons, please read this page.
positionThe tooltip position. Can be top (default), bottom, left or right. Optional.
contentTooltip content.

This code below adds tooltip to 3 fields:

#Adding tooltip for inputs

The default behavior adds tootips for field labels. Since version 1.1, the plugin supports adding tooltips for field inputs. Because of variation in the UI, the plugin supports only these fields: date time fields, text input fields (text, url, email, number, password) and select fields.

The option for this feature is tooltip_input, which accepts the same parameters as for tooltip.
