Feature form dynamic select input

[midnight-studios]

Usage

The features these changes provides can be used in different use cases of which will most commonly be utilized by plugins.

Use case example

An example will be a survey form. The admin may wish to create a form that may require numerous form input fields.

Some might be as simple as question and answer consisting of some Question Text and a feedback/answer text input field, however the admin might wish to use more complex feedback options, such as a radio group, checklist or select list. This will require the plugin to support more complex functionality as the admin would be required to add input properties such as option values and labels.

Each Form Input Item may consist of any of the following types:

• 'select'
• 'integer'
• 'html_input'
• 'html_textarea'
• 'textarea'
• 'text'
• 'checkbox'
• 'checklist'
• 'radio'
• 'fileselect'
• 'password'
• 'info'
• 'color'
• 'input_group'

Each Form Input will be added dynamically in order to build the form as needed, and each input property will also be required to be added dynamically for some inputs such as lists, may need only two or three list items, while others may be more.

This feature therefor provides support for nested dynamic inputs such as types 'select_input' inside array:array:string.

Additional use case examples will include complex settings for a shopping cart plugin, courier/shipping plugin, layer slider plugin
